Add-in Error: We could't connect to the '{0}' catalog server for this add in
Same, I am still having the issue.
Have you reviewed my reply and that of Doug Robbins?
Which Add-Ins?

It happens with multiple. The one I was originally trying to use was Agiloft Astra but now I have tried others just to see if anything works and I get the same error with Gen Text AI Assistant, Adobe, Pro Writing Aid, etc. (I've tried all of the "popular" suggestions).

Neither Doug nor I work for Microsoft. We are not seeing the problem. We both write Add-Ins. Adobe Acrobat Add-In works fine here. I have not tried any of the others you've named. I am running more that 30 Add-Ins.
Saying "I've tried all the 'popular' suggestions." does not tell us what you've tried; it leaves us guessing.
Were any of the Add-Ins downloaded through the Microsoft Store?
Have you asked the producers of the problem Add-Ins about the problem?
Feel free to download one of my Add-Ins and see if it causes the problem for you. Add-Ins
