Ignition Edge 8.3 Sync not working

Having trouble keeping Ignition Edge 8.3.1 in sync with Ignition Standard 8.3.1.

Both installations are new, and while most functionality on both sides is working well, the tag history sync keeps failing after about a week of uptime. I’m wondering if anyone has managed to keep this running reliably for more than a few weeks?

In my setup, the Edge gateway has been online for about a month. The Remote Tag Provider has been solid the entire time, and the initial sync with the Standard gateway worked fine at first. However, after about a week, synchronization stopped without any apparent cause.

Following Inductive Automation Support’s guidance, I’ve:

  • Recreated the Gateway Network connection (GAN)
  • Restarted both servers multiple times
  • Adjusted Security Zones on both ends
  • Reinstalled the Historian Core module

None of these steps restored reliable syncing. Eventually, I deleted all historical data and reinstalled Ignition Edge. That resolved the issue temporarily—again for about a week—before the sync stopped once more.

Ignition Standard is using MS SQL for historical storage, with roughly 300 tags being historized, so it’s not a large dataset. I’ve been waiting on further feedback from Support for a few days, but in the meantime, I’d really appreciate hearing if anyone else has run into this issue and found a reliable fix or workaround.
