413 "Content Too Large" error code in Surfer when using WebDav storage with Strongbox app

[d19dotca]

I was recently testing Strongbox (a password manager on macOS and iOS) and wanted to save the KeePass database file in the Surfer app's WebDAV connection. After the file grew to a certain size however, after adding favicon to all the entries specifically, it seemed to continually error out with a 413 error code "Content too large".

The size of the file approached 7.8 MB but was about 6.3 MB or so approximately in Surfer before syncing started to fail. I know I've stored files larger than that before so my thinking is this may come down to how the POST/PUT requests work or something like that.

Is there a particular limitation in upload sizes or however WebDAV works for the Surfer app? I checked and didn't see such limitations but it may be good to understand where the restriction is currently.

If anyone else has encountered this before, it'd be appreciated if they could share how they fixed it. I haven't had this issue before in Surfer and didn't see any other reports, so it may be a rare event. Any guidance would be appreciated.

Which webDAV client are you using? There shouldn't be any such size limitation and I seem to be able to upload files much larger than the few MBs you specify on my test instances.

The client is the Strongbox app but I’m not sure what dependency they may be using under the hood for the WebDAV connection itself. I will maybe open a support case with them to get more details. Just something I thought was strange and wanted to see what possible restrictions may exist in the Surfer app since it was responding with a 413. I’ll get more details out of Strongbox and come back here if I learn anything new. Thanks so much.

That is indeed odd that the app responds with 413 and there is no potential cloudflare proxying or so in between, which could get in the way?
