Issue when InfluxDB 1.8.2 behind traefik reverse proxy (http/2)

[nsteinmetz]

Hello,

I have a traefik 2.2 reverse proxy on top of my InfluxDB 1.8.2 instance.

I played with warp10-ext-influxdb, which relies on influxdb-java and I noticed that :

• with direct access, it works expected
• with traefik in between, it does not work - seems the client does not support the http/2 connection

You may not fix it as 2.0 is soon GA but at least, it may save some time for people having a similar issue.

The client talking to the http endpoint in influxdb is https://github.com/square/okhttp, please check which exact version of influxdb-java are you using and which okhttp version is in place

[nsteinmetz]

It was tested with influxdb-java 2.19 and so okhttp 4.6.0 if I'm correct.

Same behaviour with influxdb-java 2.20 & okhttp 4.8.1

[majst01]

Any logs, error messages ? from both sides

On InfluxDB side, I did not notice any particulier issue in the logs but there are some traffic on the platform.

On traefik side, no error in the logs - need to dive into access logs

[majst01]

crazy stacktrace, but access log from traefik would be helpful
