Problems connecting to Influxdb behind proxy

Grafana seems to have problems understanding the Influx version (or something) when connecting through a proxy (nifi). Simple queries works fine but when adding another query to the same panel the queries gets concatenated and only the first query works. Looking in the query inspector I can find both queries on the same row, like:
“SELECT bla bla bla;SELECT bla bla bla”
Is there any response headers missing that confuses Grafana?

Thanks

Found the problem myself. Several queries are separated with “;”. If that’s not properly URL-Encoded Influx ignores the part after the “;”
