Consensus not signed by sufficient number of requested authorities

Hi all!

I have Tor (just Tor only) version 0.4.6.10 running on Linux. It is NOT a relay, just a client. It uses bridges (obfs4 or webtunnel) and it worked well for a long time. But recentry I had to re-install OS. Now Tor can’t establish connecition.

The typical log is like:

Jul 18 10:53:04.000 [notice] Bootstrapped 30% (loading_status): Loading networkstatus consensus

or (with another transport):

After all:

Jul 18 12:07:23.000 [notice] Application request when we haven't used client functionality lately. Optimistically trying known bridges again.

and connection failed.

Bridge or transport changing has no effect. Cache clearing etc does nothing too. But I noticed that Tor Browser with the same bridges works well.

I investigated the forum and found these topics:

ans also:

but found nothing to help (or, maybe, did not understand :))

How can I fix it?

First and foremost update to current version 0.4.9.11

Older Tor versions need to be updated before 2026-09-01:

This tor version is no longer supported.
Please, update to the latest one - 0.4.9.11
