Hello, site is not opening. It is written that too many * redirects*.
How to solve?

Hi @Anastasiia
You have a problem somewhere in your reverse-proxy. It is not possible to know anything more besides that with the limited information you're providing.

Hello, @flamber! Thank you for the replay.

Most likely it has happened due
to the issue described here Can't turn off HTTPS redirect · Issue #13084 · metabase/metabase · GitHub. If there is a fix for this, in order to keep all the dashboards and queries?

@Anastasiia If you read my first comment, then it includes a workaround:

It is caused by your reverse-proxy not sending the correct headers.
