Steps to Reproduce

Good afternoon, I installed CVAT in a personal server to run on localhost. The initial idea is conecting to it from outside the local network using remote.it, however I cant manage to access it.

I installed CVAT following the documentation, to set it working on localhost:8080, tested it with curl:

~/cvat$ curl -I 127.0.0.1:8080
HTTP/1.1 200 OK
Accept-Ranges: bytes
Cache-Control: no-cache, no-store, must-revalidate
Content-Length: 1265
Content-Type: text/html
Cross-Origin-Embedder-Policy: credentialless
Cross-Origin-Opener-Policy: same-origin

Pragma: no-cache
Referrer-Policy: strict-origin-when-cross-origin
Server: nginx
X-Content-Type-Options: nosniff
X-Frame-Options: deny

Appears to be working properly, I set up the remote.it connection:

 90:00:00:00:00:xx:xx:xx| HTTP (7)          | connected    | 127.0.0.1:8080           | true

But when I try to connect from outside, like I do with other servers that I have running (with FastAPI), the website doesnt load stating 404 page not found.

I setted the log level to debug, and this is what I found:

{"ClientAddr":"172.25.0.1:43158","ClientHost":"172.25.0.1","ClientPort":"43158","ClientUsername":"-","DownstreamContentSize":19,"DownstreamStatus":404,"Duration":12552,"GzipRatio":0,"OriginContentSize":0,"OriginDuration":0,"OriginStatus":0,"Overhead":12552,"RequestAddr":"cvat.at.remote.it:33009","RequestContentSize":0,"RequestCount":1,"RequestHost":"cvat.at.remote.it","RequestMethod":"GET","RequestPath":"/","RequestPort":"33009","RequestProtocol":"HTTP/1.1","RequestScheme":"http","RetryAttempts":0,"StartLocal":"2024-06-20T11:39:59.448325222Z","StartUTC":"2024-06-20T11:39:59.448325222Z","entryPointName":"web","level":"info","msg":"","time":"2024-06-20T11:39:59Z"}

cvat.at.remote.it:33009 is the IP I use to connect from my local device, which then gets translated to 127.0.0.1:8080 with the remote.it service, but aparently its not working.

Any advise is welcome,
thanks

Most likely you just need to set a correct CVAT_HOST
