Croc won't send files

[claytankozmo]

It worked several dozen times in the past, and all of the sudden wouldn't. I have updated croc using scoop to the newest version, uninstalled and reinstalled with no luck.

Same issue here! Using croc version v10.0.11 on Ubuntu 20.04.6 LTS:

It works, though, on a mobile network, using my mobile phone as an access point. So it seems that the error is network dependant.

UPDATE: I found the problem while reading https://github.com/schollz/croc/issues/773
So, I used my own relay and the problem was gone!

Hi @nabadvin + @claytankozmo

It appears that the public server is currently at capacity from the sender IP address. When LAN connections aren't established and users aren't utilizing their private relay, the system defaults to the public server. The bandwidth usage of the public server incurs monthly costs for me, leading to a limit on the data that can be sent.

If you could sponsor me on GitHub, I'd be happy to remove this limit for you: GitHub Sponsor.
