Import dashboard from Grafana behind firewall

[pgloader]

Problem/Motivation

My Grafina server is behind company firewall. When I tried to import https://grafana.com/grafana/dashboards/12086, it seemed failed with Bad Gateway. In the log there was an entry like "t=2022-03-31T10:49:00-0400 lvl=eror msg="Request Completed" logger=context userId=1 orgId=1 uname=admin method=GET path=/api/gnet/dashboards/12086 status=502 remote_addr=10.24.109.31 time_ms=51 size=0 referer=http://ll-lt-ixcsdb-01:3000/dashboard/import"

Expected behavior

Actual behavior

Steps to reproduce

• -> Import -> put 12086 in the Import via grafana.com field -> click Load

Proposed changes

Instruction how to fix the issue
