This has happened to me sporadically, and I just updated to version 1.7.0.beta2 and it’s still happening. Seems similar to Sporadic missing letter avatars (cache problem?) but maybe not the same thing?
What happens is that from time to time, the letter avatars don’t appear correctly. It used to be that none of them would show up, and I’d just reboot the VM which seemed to fix it.
Today though, I was having issues with just two (T and A). And then randomly J started showing up, with just T being an issue now. We had a power failure last night so the VM was just started this morning, and then I upgraded Discourse to the latest version. That’s the only info I can think of that might be relevant.
The following appears in the console:
Failed to load resource: the server responded with a status of 502 (Bad Gateway) http://feedbackloop/letter_avatar_proxy/v2/letter/t/f05b48/25.png
If I go to the image URL, I just see
502 Bad Gateway
If there’s any other info I could provide that would be helpful to troubleshoot, please let me know! I won’t rebuild the app or reboot for a little while just in case.
