Unknown Error when viewing email message
Rainloop version 1.16.0 Browser: Firefox 96
Whenever I get an email sent from a Synology NAS or TrueNAS, I cannot open the email message. It just says unknown error in the message. This behavior does not occur on other received emails (like from debian, or from zabbix).
There is no errors in /var/www/rainloop/data/data/default/logs/ and no other errors in syslog in general.

I also have the same issue since today for ALL emails, getting a list of my emails work, including showing which emails are new. But once I select and want to view a specific email, I get an Unknown Error. Sadly I cant see any errors in the logs either. It is just not listed anywhere.
But in my browser in the network devtools tab I can at least see a 500 for the request https://mail.domain.tld/?/Ajax/=&q[]=/RANDOMSTRING/Message/&q[]=/RANDOMSTRING. I Would love to provide more logs, but I dunno where I could see them :thinking:
I did just upgrade my lxc container from Debian 10 to Debian 11 yesterday, but I also rebooted my full machine afterwards and I am sure it still worked until today in the morning. Makes me wonder if this is related to that or if maybe mailbox.org (my mailprovider) changed something.
I did "fix" this issue by just making a new container, this time based on Arch Linux (btw) instead of Debian 11. I dunno, I guess maybe a package that got updated when I updated from Debian 10 to 11 broke something? And maybe I did not notice it until today because stuff was still cached? I dont know :woman_shrugging: With a clean nginx + php-fpm installation on a fresh Arch Linux it does all seem to work.
