Can't login to Router (10.0.0.1) with Safari MacOS 15

I can no longer login to my Router with MacOS 15.0.1 and Safari 18.0.1. Works fine with FireFox and MacOS 15.0.1. Worked fine with MacOS 14/Safari.

I just get a blank page that says:

Safari can't open the page "http://10.0.0.1/Main_Login.asp". The error is: "cannot parse response" (NSURKErrorDomain:-1,017)

Any ideas?
 
It is an error message that has numerous causes, so quit hard to diagnose. But mostly do the by disabling stuff. What I suggest:

Follow the steps here https://support.apple.com/en-au/102564 And where it says "Check VPN or other security software", the other will include 3rd party AV, firewalls, etc.

But I would start by disabling all Safari extensions and iCloud Private Relay.

There are couple things in that link I haven't tried yet. I will later tonight. Thanks.
 
I spent another hour trying to find a solution but failed.

It seems the problem has "something" to do with "content blockers", but the behavior is so inconsistent it's hard to explain.

I only had one Safari Extension loaded, and that was Ka-Block!. Turning it off, trashing it, didn't help.
Private relay on or off, makes no difference.

Here's a long description of what happens:

When I try to login to an ASUS Router (latest firmware) I get a blank page with only the Error Message ""cannot parse response", etc. that I quoted at the top of this thread. Occasionally (like after rebooting MacOS), I get the normal Router login page and I can log in. But then most of the other setting pages don't load correctly and eventually I get a blank page with the Error message again.

The FIRST time I try to login with a Safari Private Window, I get a fully formed Router login window, and then I can login into the routers "home page".

AFTER the FIRST time I try to login with a Safari Private Window that doesn't work again until I close Safari and reopen. Otherwise I get the blank page and Error message instead of the Login Page.

When I do manage to login and move around in the router's settings pages, some pages come up with missing portions of the page (usually menus), and some pages come up blank except for that same Error Message. When either of those things happen, I can sometimes click on View/Reload WITHOUT Content Blockers and the page is refreshed correctly. But then when moving around in the settings page the problem comes back. What is weird is that then I can click on View/Reload WITH Content Blockers and that can sometimes restore the page correctly.

i.e. sometimes one or the other of Reload WITH Content Blockers or Reload WITHOUT Content Blockers can temporarily get a page to reload correctly.

NOTE: The router firmware is up to date, as is MacOS 15. The problem started AFTER updating my Mac Studio to Sequoia 15. I get the same behavior with Safari or a fresh copy of Safari Technology Preview. The router web interface works perfectly with Firefox and MS Edge browsers. Also works perfectly with older Mac OS/Safari on Mac Pro, Mac-mini and MacBook Pro (unfortunately can't run MacOS 15 on any of those to test). It also works perfectly from my iPhone running the latest iOS.

I'm stumped.

After trying all that to no avail, you are left with the conclusion that latest Safari is unable to parse output from your Router. All I can suggest:

1) Name your router model - to find out if others have the problem.

2) Apple Feedback as a bug specific to latest Safari and router model.

3) Alert the router manufacturer to the issue.

4) Use the workaround (different browser).

Yep, seems Apple did something to the current version of Safari (18), which is also the same in the latest Safari Tech Preview (18), that is now incompatible with the Router Web Interface. Just strange that it would break a simple web interface that has been around basically unchanged for so many years (i.e. not using anything particularly new).

1) ASUS RT-AX88U Pro (My bad, I thought I had named it in my initial post - but I didn't)
2) Already done
3) Will do
4) Of course that is what I am doing

I have exactly the same problem with the RT-AX88U Pro, works fine with Chrome. I traced the issue and it seems to be Safari stating that some of the router pages cannot be found.

Will have to wait for ASUS or Apple support to wake up to the issue and fix.

I'm sorry we are both having the problem, but I'm glad to hear I'm not the only one. I was thinking it may be caused by some sort of malware if I was the only person to report it. So maybe not.

Since I posted above I have "discovered" a number of things. I'll document (it's long) what else I've done below in case more people have this same problem.

As an experiment, I set up a completely new MacOS 15 Parallel's Virtual Machine within MacOS 15. With the completely bare new OS 15 VIRTUAL MACHINE there is NOT a problem. The router pages seem to load correctly all the time. That made me concerned that my actual MacOS 15 has some malware, or at least some corruption within the OS (I had previously tried trashing about everything I could find related to Safari in the Library files and downloaded fresh versions of Safari Technology Preview without fixing the problem - so I don't think Safari itself is corrupted.)

So then I set up a completely new MacOS 15 as a Dual Boot Volume on my Mac Studio. At first I didn't load anything into it from the previous MacOS 15 volume. When I booted into the new MacOS 15 I didn't notice any problems with the router pages. Then I used Migration Assistant to copy over the System and Network settings from the "bad" OS 15 volume, and that "broke" the "NEW" MacOS 15 volume in exactly the same way as the original volume. I either couldn't get router interface login page at all, or I could login using a Private Safari page, but then some pages wouldn't load completely or not load at all after that. So again I assumed something was corrupted in the original OS 15 volume and I had copied it over into the new OS 15 volume.

So I completely erased the 2nd OS 15 volume and created a new "3rd" OS 15 volume. Again it seemed to work fine with the router pages at first. So this time I used Migration Assistant to copy over ONLY my Apps. Then I was still able to get the router login page but I occasionally get a router page that only partially loads. When that happens I can just reload the router page and that fixes it (I was never able to do that with the original OS 15 volume).

So I'm still baffled about what is going on. I've gone into the Launch Daemons and other "helper tools" and trashed everything I can that runs in the background (thinking that loading the applications started some new background processes that are interfering with Safari, but that has not changed what happens with any of the OS 15 volumes I've tried).

Nothing except an absolutely new OS 15 install seems to work perfectly, although my 3rd volume install with just apps moved over works almost every time so far. But I'm reluctant to spend hours "restoring" the new volume to the same level as my original OS 15 volume (it takes hours getting the Mail app setup with my many Smart Mailboxes and Rules because iCloud sync of multiple non-iCloud mail accounts has never fully worked to do that - not sure its intended to), and then somewhere along the way have the 3rd OS volume just break completely like the 1st OS volume.

Bottom Line for Now

So at this point I'm inclined to give up trying to find the cause (since I can login to router perfectly with Chrome, Firefox, or MS Edge), and just go on using my original OS 15 volume. I was concerned the problem was caused by malware messing up Safari, but since I don't see any other "effects", and you also have the problem, I guess I'll ignore it for now. And hopefully it is just some really difficult to understand OS 15/Safari/Asus Router incompatibility that will eventually be fixed when one of them is changed again.
 
Just wondering if you have the built-in firewall enabled? It's causing a ton of problems in 15.0.1. I had to disable it to get some applications to function properly that were working fine with it enabled in 14.

Oh, yeah. One of the first thing I tried. No effect turning it off.

It's interesting that if I press the reload button in Safari the login page will appear and I can login to the router. The issue then changes to a malformed portal page where elements aren't loading correctly, the developer console reports the parsing error against the device-map/router.asp file. If I select one of the menu items on the left the screen changes, but elements are missing, I then logoff and the -1,017 message is generated again.

I actually think the issue is a Javascript integration issue with Safari 18 and 18.0.1.

Yes, I've seen all of that and many more inconsistent things that I described above. Also starting from a Private Safari page always provides the complete login page that works (but not from a non-private Safari page), and then it still messes up creating partial pages or a blank page with the -1017 error up while moving between the web interface pages.

Perhaps, but how could that explain why Safari and MacOS 15.0.1 work perfectly inside a Parallel's Virtual Machine also running in the same MacOS 15.0.1 host? It should be the same Javascript integration inside the Virtual Machine as outside the VM. The fact it works perfectly in the virtual machine should be a clue to someone more knowledgable than me.

Anyway, I've wasted several days on it and I'm going to ignore it now and move on (plenty of workarounds by using other browsers).
