Ice connection keeps switching from connected to disconnected

[Tinouga]

What version of this package are you using?
0.107.3
What operating system, Node.js, and npm version?
12.8.0

Hi,
Here is my problem: right after one peer starts sharing and another starts leeching (sometimes a few Ko of data are shared and it stops right after), the state of the ice connection keeps switching from connected to disconnected.
Could anyone point me to where should I look in order to fix this problem?
(The strange thing is that everything worked fine on my website until I made a git fetch/reset to update a few files with nothing (if I'm not mistaken) related to webtorrent)

Thanks a lot for your help!

edit: after turning off/on my CPE (I hope it's the correct translation for "box internet") once again, everything works fine now

Glad you got your issue resolved. Connection issues depending on network conditions are unfortunately part of life in distributed systems like WebTorrent.
