@edalcin Did you use the Docker image? Other than that this is not much to go on, I don't use Unraid, so I can't really tell what the issue might be.

Closing due to inactivity.

@sissbruecker I had the same issue using docker-compose on debian. In fact this had nothing to do with the host but with the client.
Using firefox in private mode (no addons) it worked. However with all my addons I got the same error message.
"invalid request block size: 4388 (max 4096)"

According to this:
https://topic.alibabacloud.com/a/when-uwsgi-is-deployed-to-nginx-invalid-request-block-size-4161-max-4096-appears_8_8_20029027.html
The header size of uwsgi by default is only 4k.
Upping it to 8k by adding this line in uwsgi.ini:
buffer-size = 8192
solved the issue.

[sissbruecker]

@elmodor Thanks for debugging this, I guess increasing the header size in uwsgi should be no problem. I'll reopen this.
