I am running roundcube and nextcloud-aio on the same docker environment. Both are on the same tld, but both are behind an nginx reverse proxy. I have followed the instructions on reverse proxy setup and I have an alias at nextcloud.xxxx.com/roundcube that functions, pointing to roundcube.xxxx.com. Everything works on the roundcube side.
The plugin loads roundcube properly and authenticates. I can see all of my folders but no emails are loaded. There's a red toast that reads "Server Error! (parsererror)" which pops occasionally. I've look at the nc logs and there's nothing reported, even on debug. The roundcube container doesn't have any errors:

Which are just get and post requests. There's absolutely nothing in the nextcloud or nextcloud-apache containers. I have no idea where to even start with this issue, so some guidance would be appreciated.
