Hello,
I have a multi-container app running on 2 raspberry pi’s (first is a rpi4, the other is a rpi3b+). No problem on the rpi4, everything starts up as expected.
However, on the rpi3, some containers fail to start. They seem to be stuck in a loop where the logs report “Starting service…” over and over again.
By running journalctl -n 50 -f -a -u resin-supervisor I could identify that there are errors happening:
Jul 29 13:12:55 cae5e45 resin-supervisor[5609]: [error] Scheduling another update attempt in 2000ms due to failure: Error: Failed to apply state transition steps.

(HTTP code 500) server error - driver failed programming external connectivity on endpoint smsl-screen_2554060_1477104 (37f3bb6ee222ccf84bb744ba2939c51c13589815fdabc917c34dbc77fcd8f642): Bind for 0.0.0.0:80 failed: port is already allocated Steps:["start","start","start"]
Both of those ports (80 and 9090) are forwarded to/from my containers for communication with other containers.
I tried some of the solutions mentioned here but none worked so far.
Any help would be appreciated!
