Multiple connection requests from same device with alternating IDs

I have SyncTrayzor on my Windows computer and Syncthing Fork on two Android phones. They will get synced only locally via WiFi.

Today I tested SyncthingTray while SyncTrayzor was running. Perhaps that was not a good idea. I don’t use SyncthingTray any more and the next time I connected the three devices via SyncTrayzor and Syncthing Fork the computer, while being connected already, began to ask for connecting to the phones a second time with a different ID but same name and same folders. I rejected and after a short while it asked again with another ID. What does that mean? What went wrong and how can I fix that?

I noticed two syncthing.exe processes in the Windows Task Manger with the same command line. Is that normal?

Syncthing does have two processes by design, this is normal.

Forgive me for speculating; I’m pretty new to Syncthing: While I’m not at all sure what happened to you, it sounds like it could have been:

  1. SyncthingTray installed another instance of Syncthing
  2. The new instance of Syncthing created its own ID (and corresponding cert)
  3. …and somehow picked up the configuration of your original Syncthing instance, AFTER creating its own cert
  4. And keeps doing that?

But truthfully my hypothetical seems really unlikely to me.
