iMessages not working after iOS 17.1 upgrade

[Aboo]

I like many others upgraded to iOS 17.1 yesterday. I also upgraded my Mac to the newest version of OS Sonoma. Since doing so, I’m noticing that both on the Mac, as well as on the iPhone, I am unable to send iMessages. I seem to be able to receive them fine however, when sending, I got a red exclamation mark Stating “failed to send“. The phone seems to automatically resend it as a regular text message. I tried resetting the network settings. I tried turning on an off airplane mode. I also hard rebooted the phone without avail. Thoughts on what could be going on?

First, on iPhone > Settings > iMessage > (turn off) and then
on Mac > menu Messages > Settings... > iMessage > (Sign Out) of Apple ID

Now, reverse.. on iPhone (turn on) iMessage and then on Mac (Sign In) Apple ID in Messages > Settings.

Thank you, I just tried your suggested steps, but no luck. I do have more than one Mac that I am signed into. Do I have to sign out of each Mac?

Thank you!

Just to provide an update - I reached out to Apple and after extensive troubleshooting, they have escalated the issue to engineering. Interestingly, things seem to work fine on a Mac that has not been upgrade to Sonoma, but only specifically being blocked on Macs with Sonoma 14.1 and iOS 17.1.

Unfortunately, this situation has just shown me how dependent on iMessage I am through the course of both personal and professional interactions in life!

I will update back when I get any further input from Apple's engineering team.

Still no updates from Apple engineering. Have had them check to see if my phone numbers or email addresses were inadvertently added to the blocked list, and that is not the issue. If anyone has thoughts, please help

Still no resolution

Have you tried Erase All Content and Settings then restore from backup?

I've been having Messages issues as well since 14.1.

Everything's fine on my phone, but not all Messages are coming thru on my MBP.
