@Jheks That log looks strange and I didn't got such error. remocolab always download latest cloudflared and its download URL match to latest version.

I got different error and I have fixed cloudflared related code and remocolab works with it for me. Please test latest remocolab and let me know if it work.

no RunTimeError now but failed to connect to the ssh server:

ssh -o UserKnownHostsFile=/dev/null -o VisualHostKey=yes -oProxyCommand="cloudflared access ssh --hostname %h" colab@treaty-sing-continuous-religion.trycloudflare.com /bin/sh: 1: exec: cloudflared: not found kex_exchange_identification: write: Broken pipe

don't know how to fix this
