Updating Grafana 8.0 : connection to server is lost

[dominikbauer217]

Hi guys,

after updating grafana to 8.0, i get the following alert warning on my main page:

I did not changed any of the default.ini settings.
I’m running grafana behind a reverse proxy.
When i change the domain name to “localhost”, everything works fine with the original IP-Adress.
I think the proxy settings in grafana and nginx are right, because it worked with previous grafana versions.

Best Regards,
Dominik

Got it.

Its because of missing Websocket Connection and the new Grafana Live Addon.
Just set max_connections = 0 in defaults.ini

#################################### Grafana Live ##########################################
[live]
# max_connections to Grafana Live WebSocket endpoint per Grafana server instance. See Grafana Live docs
# if you are planning to make it higher than default 100 since this can require some OS and infrastructure
# tuning. 0 disables Live, -1 means unlimited connections.
max_connections = 0
