I have read 20 - 30 threads about this error, but still i cant solve mine.

Since a few days this errors pops up by accessing sharepoint over https trough tmg 2010.

Who can help me, i cant fiend a solution for this weird problem.

i can reach my sharepoint server from tmg, certificate is also ok, names in the certificate also.

I have installed no update the last past days and also havent changed anything yet

i have read some forums about the netwerk trace monitor, but i cant find anything there?

Hi,

Have you read these articles before?

If you are publishing SharePoint, you need to configure AAM properly.

Meanwhile please check if you disable web proxy filter, does the issue persist?

Thansk for your reply,

the sharepoint aam is nothing changed. So this cant be the problem

also on the tmg side i  have nothing changed. It happend from one to another day.

I have read the blogs: 

1. missing some screenshots

2. I have nothing changed on tmg and sharepoint

3. certificate is ok

4. web https inspection turned off

i have checked with fiddler:

also under authentication in fiddler:

No Proxy-Authenticate Header is present.

No WWW-Authenticate Header is present.

no one can help?
