VRM Dashboard Error #150 - Live Data failing, but Remote Console (MQTT) works

Hello Victron Support / Community,

I am experiencing an issue where my VRM Dashboard is no longer showing live data. I receive the following error message:
“HTTPS channel #150 unexpected response text”

System details:

  • Device: Cerbo GX

  • Firmware: Tested on v3.72 and downgraded to v3.71 (issue persists on both).

  • Connection: Mobile (PPP) - Data link status is “Connected”.

What I have verified:

  1. Remote Console: Works perfectly via VRM, which confirms the MQTT RPC and Real-time channels are connected.

  2. Time & Date: Perfectly synced and set to NTP.

  3. Real-time updates: Enabled in the GX settings.

  4. Browser/App: Issue occurs in both the VRM App (iOS/Android) and via web browsers (Chrome/Safari), even in incognito mode.

It seems like the HTTPS data stream for the dashboard widgets is being rejected or incorrectly formatted by the server, while the underlying MQTT connection is stable.

VRM Portal ID (moderated only share the site number of the portal url)

Could you please check if there is a server-side issue or a database mismatch for my Portal ID?

Thank you in advance!

Do you have any modifications loaded? What physical connection are you using? Are you using both interfaces?
There are a few topics on this subject available via searching as well.
It usually resolves by itself after a few hours.

Hi Nick,

I am not running any mods.

I am using a GX LTE 4G with a odido data sim card.

I am not using an ethernet cable. The system is only connected via the gx lte 4g modem.

Hope this helps!

Ok, thanks. Might just be a localised network issue. As mentioned, these errors tend to resolve themselves.

similar topic: HTTPS connection error #150 "Unexpected response text" since this morning — MQTT works fine

My take:

Just to add another data point — this does not seem to be related to modifications or connection type.

I’m managing 100+ installations and have been seeing this error (#150 “Unexpected response text”) quite often recently across multiple systems.

From my experience:

  • Happens on completely stock systems (no mods)

  • Occurs on:

    • Ethernet-connected sites

    • Wi-Fi-connected sites

    • LTE/4G connections

  • Across different ISPs/providers

So it’s very unlikely to be a local network issue.

There are already multiple topics reporting the same behavior (including the one linked above), which further points to a broader issue.

Observed behavior:

  • MQTT (remote console & real-time data) → works fine

  • HTTPS/VRM logging → fails with error #150

  • Usually resolves itself:

    • often within hours

    • but sometimes takes days

Impact:

  • Data accumulates on the GX device - needs to have SD inserted, otherwise lost

  • VRM graphs and historical data lag behind

What I’ve tested:

  • Reboots → no consistent improvement

  • Toggling HTTPS/SSL → no effect

  • Switching networks/providers → same issue

Given how widespread and consistent this is, it really looks like a server-side issue (possibly incorrect response from VRM endpoint) rather than anything on the installation side.

Would be great to get:

  • confirmation from Victron

  • clarification of root cause

Right now it just sits in error state until it recovers on its own.

Thanks.

Can you share some vrm id’s? Just the digits in the url.
We have an idea why this happens.
