Hi,

Since approximately 5:00 AM CEST today (April 3, 2026), my GX device has been showing #150 Unexpected response text on the HTTP/HTTPS channel. MQTT Real-time and MQTT RPC channels are both Connected.

What I’ve tried so far:

  • Enabled HTTPS — same error

  • Rebooted the GX device — no change

  • Connected via mobile hotspot (different ISP/network) — same error

  • Navigating to http://ccgxlogging.victronenergy.com/log/log.php from a browser on the same network returns “vrm: fail”

System info:

  • 3x MultiPlus-II 48/5000/70 GX (three-phase system), firmware v3.72

  • Date/Time UTC correct: 2026-04-03 11:15

  • Time zone: Central European Standard Time

  • Connection: Ethernet (also tested Wi-Fi hotspot)

Since the VRM logging endpoint itself returns “vrm: fail” rather than a captive portal or redirect, this seems to be a server-side issue. I noticed a similar report from March 29 that resolved itself after a few hours.

Is anyone else experiencing this today? Any guidance appreciated.

Thanks!

Update: The issue resolved itself after approximately 12 hours. No changes were made on my side — VRM HTTP channel started working again on its own.

This confirms it was a server-side issue, similar to the report from March 29. MQTT remained connected throughout.

Thanks for any attention to this. Closing the topic.
