icecc fails to transfer files to remote machine

[LorenDB]

I'm trying to set up a two-node cluster (consisting of my personal laptop thinkpad and my work laptop duna). When I try to send a compile job from one machine to the other (and I have observed this with jobs originating from both machines), the jobs are successfully sent and show up in icemon, but according to icemon, the actual source files are never sent to the remote machines; icemon remains at 0 B in for a while and then the job fails. I don't observe any high processor or memory usage on the remote machine, which further confirms that icecream never reaches the compile stage on remote machines.

Details of my setup:

• Personal laptop: Lenovo Thinkpad X1 Yoga with 11th gen i7 and 32 GB RAM
• Work laptop: Alienware m16 with 13 gen i9 and 64 GB RAM
• The laptops are connected via a mobile hotspot (janky, I know, but it's what I have).
• The laptops are connecting to each other properly; it doesn't seem to be a firewall problem.
