Server did not respond to client hello

Hi Atif Zafrak

Please share the error message you are getting while accessing the website ""https://www.researchgate.net/"

Apart from web filter logs did you check Application logs under Log Viewer?

Thanks and Regards

Hello,

There was no problem in the web filter, but I noticed that it was dropping in the Application Filter. It's really funny that I checked everywhere and skipped it.

I solved the problem by giving permission from Application Filter. I probably thought that the exception permissions would exceed the web filter and application filter, so I didn't focus too much on those parts.

I though so as same website is under Social networking category on Application filter 

Yes, it was blocked here. I solved the problem by giving permission.

I thought the rules here would crush the web filter and application filter, but I was wrong.

Additionally when I use SSL /TLS filtering, sophos does not receive firmware updates.

With exceptions, you can override protection settings for all web traffic that matches the specified criteria, regardless of any policies or rules in effect.

For example, you can create an exception to skip HTTPS decryption for sites that contain confidential data. The default set of exceptions allows software updates and other important functions for well-known websites without being affected by web filtering.
