(SOLVED) Wifi Sync stopped working on a device

Update Final: I found the problem on my end but Enpass does not lend itself well to basic troubleshooting. I echo the sentiments of others who would like to have a MANUAL SYNC, a way to STOP A SYNC once it's started (my phone takes forever to sync and even after putting it into airplane mode I had to walk away to I wouldn't throw it against the wall in frustration) and those teeny tiny fonts are super hard to read, especially for people with old eyes). Lastly, I find it somewhat annoying that I need to create an account on a platform I never use to get support for a product I paid for.

Update: After exhaustive troubleshooting, it seems like the problem is with the receiving PC as I was able to install and use wifi-sync on a test device. The issue insofar as I can tell is the receiving PC is not discovering the wifi-sync server PC. Is there a way to manually set up the wifi sync and tell the receiving PC what computer to look for on my network? Since it appears you've shifted support to reddit, and I don't have a reddit account, I'm hoping someone will eventually read this and respond.

Wifi sync stopped working on my receiving computer. Sync works fine from the server to my phone, just not to the computer. I've exhausted all my available troubleshooting resources. Router rebooted, firewall rules rebuilt, Enpass reinstalled multiple times, app data removed, network configuration reviewed and extensive testing performed. At this point even Microsoft Copilot has stopped returning my calls. Here's what I know or have done conclusively:

1. Stopped yesterday.

2. Windows 11 (on host PC and receiving PC).

3. Infinite "Looking for servers..."

4. Reinstalled multiple times.

5. Deleted all Enpass data.

6. Reset firewall rules.

7. Rebooted router.

8. One time only, the server was the host via an IPv6 address, but the result was not repeatable.

As far as I know, Wi‑Fi sync worked reliably for 4-6 weeks but I noticed on 10/22 it wasn't synchronizing some changes I made on my laptop. When I forced a sync, the receiving PC immediately came back with SYNC COMPLETE but no data was updated. I first uninstalled Enpass and reinstalled it but from that point, I could not get Wi-fi sync to work. The Windows 11 client remains indefinitely on "Looking for servers...". The issue appears to occur during server discovery rather than during connection or synchronization. Reinstallation, firewall reset, application data removal, and router reboot have not resolved the issue. During testing, a second computer once discovered the host via an IPv6 address, though the behavior was not repeatable.

I saw a thread with reporting similar (from 2025), but I think the solution or issue had to do with virtual adapters, which is not the case with my PC. I have log files if needed. I look forward to hearing a response from tech support.
