Do you have TMG client installed?
Open logging on TMG, filter it by googleupdate.exe and find rule preventing updating.

If you have authorization on TMG, you had to use TMG client.

You may have problems when client software (google update, for example) can't use authorization. In this case may be better not to use "Require all users to authenticate". Read these articles:

Have you tried to allow traffic to tools.google.com? Anonymous access - All users

It is kind of working now.


The problem is is taking too long to "verify" chrome version. Without proxy it is very very quick.

Before all changes, it used to take very long time and ended in error. Now after very long time it returns that my version is ok, but logging it still have some denied connections.

I think we are almost there!

I sill didnt understand how do i allow anonymous access! Just grant all users?

Yes, to all users. Is it blocked with the same rules as before? Both errors (12209 and 12202)?

Very good. Usually you should close session before changes will work.
