Syncthing has stopped syncing...cannot identify the issue.

A couple of months ago my Macbook Pro had what appeared to be an unusually hard finder crash. After the dust had settled and I completed repairs, I noticed SyncThing had stopped syncing.

As I attempted to work through the issue, I noticed that my version (1.6.1) was far behind the current version (1.27.10), that has been addressed...SyncThing version update, seeming version contradiction...

The update did afford one benefit to this issue, it returned the browser interface, which would not appear prior to the update.

Behavior:

The SyncThing menu cycles between two states, Unavailable and then Running Offline ( refer to attachments ). Selecting any of those options in the drop down menus has no affect. The cycle is about 4 to 5 seconds.

During the cycle, a Connection Error is shown and then vanishes, then reappears, etc. My attempt to remove and then reinstall SyncThing ( above ) did not stop the problem. Pausing SyncThing does not affect the cycle.

The other machine, Mac Pro is not affected, other than not syncing with the MacBook Pro and simply shwos the MacBook Pro as disconnected.

I am completely stumped. I have no idea how to fix this.

I am running Ventura 13.6.9 (22G830)

No source file, test, or entry point is identified. Start by reproducing the cycling Unavailable/Running Offline states on macOS Ventura 13.6.9 after the reported reinstall, then trace the connection error and compare behavior with the unaffected Mac Pro. Done means identifying the cause and restoring syncing on the MacBook Pro.
