[Bug]: Upload Large file fails

[Silther]

What happened?

Often when uploading a new books via remote connection (Wireguard or reverse proxy caddy) the upload fails on large books.

But if i try to upload the same book via Wireguard and ssh (scp local server) it works without any issue.
It takes around 5-10 min but no connection error or something else occurs.

I am not completely sure if it only happens with additionally an slow internet connection, but it may be so.

What did you expect to happen?

Upload of large books (with slow internet) should work without any problems.

Steps to reproduce the issue

0. (have slow internet connection
   

1. upload book with around 1gb size

2. upload will take for ever (30+ min) and then fail

Additional Notes

I have changed the file limit of caddy, but that did not change anything, wireguard should work non the less but it does not work too.

if i'm in the local net uploads to the server (via ip) work without problem.

[advplyr]

Typically if it works locally then it is not an issue with Abs and it is a user network issue. That is because Abs doesn't have to know whether you are running locally or not, it is responding to requests the same.

That is not to say there is nothing we can improve or that it isn't possible there is an issue with Abs but to know if that is the case we need specific details on recreating the issue that doesn't require replicating your network setup.

[Silther]

that's why i think it could have something todo with network speed and the way abs handles slow connections and timeouts.

if I connect my device via Wireguard, abs should behave the same as locally but it does not.
And uploading my books to the same server via ssh and wireguard works without problem.

will test it sometime again with an faster internet connection from remote.

[pwinnski]

if I connect my device via Wireguard, abs should behave the same as locally but it does not.

The result is different, but ABS is behaving the same.

ABS has no idea whether you're connected locally or via reverse proxy or any other way. It always behaves the same way. So if you see different behavior, that is the result of the different network configuration, not a result of ABS doing anything different.

As advplyr said, it's possible ABS could handle uploads better than it does, but the first step would be to isolate what the issue actually is.
