hi, having same issue too

Hi @dginhoux could you provide me with more details how to reproduce this issue?

Is everything was ok on the previous 0.19.3 version? On which latest version did everything work well?
Do you use vmauth?
Which version of VictoriaMetrics do you use? cluster or single?

If you can reproduce this bug on playground, it will be great. I'm trying to reproduce this problem, but I'm not getting anywhere yet.

Hi,

Yes... I've not have just this behavior since 0.19.x release. For me rollback to 0.17.0. (already try to downgrade grafana without success).

Grafana is 12.2.0.

Im using vmauth as front-end for Auth per tenants.

all components are up to date and updated 3/4 days after each release date, I don't remember but it's 127 I think.

@dginhoux , do you have this problem on version 0.19.5?

Oct 27 '25 11:10 arturminchukov

At this time, i think the problem is still present but not sure, it's this problem now...

If you want try, i can quiclky start and publish an instance (grafana 12.2.1/vmsource 0.19.5/vmetrics 1.127) and give you adm access for debug.

@dginhoux do you use the v1.127 of vmauth and cluster version of victoriametrics?
