Thank you so much for the report @paul8046! I can confirm that I was able to repro this by following your repro-steps:

8-08T05:09:25.643-0400    INFO    main    lotus-worker/main.go:531        Opening local storage; connecting to master
2023-08-08T05:09:25.659-0400    WARN    main    lotus-worker/main.go:114        dial tcp: address ::1:2345: too many colons in address

I have put up the issue on our Sprint planning board https://github.com/orgs/filecoin-project/projects/92, and I will try to shcedule some work on this in the current sprint if we have some spare cycles, else it should get some work done in the next sprint.
