this looks to be an error with a mismatched server and client version im imaging, what version is your app and what version is your server?

p.s its totally fine to spam errors they help us prevent them later down

Do you use HTTP or HTTPS to connect, and did you specify that in the Drop client?

I just spun up Traefik to see if it was an issue with it, no dice.

I'm out of ideas. Basically, something is getting between the client and server, and probably showing some sort of error/HTML page. If you can access by direct IP or something, that'll probably work.
