Skype files download issue.

[AzerbaijanSupermarkets]

Good day!

After the recent update Skype stop to function normally, I can upload, but can't download any file.

Temporary solution was not to decrypt this category - "internet-communications-and-telephony".

But I don't think that this is a normal solution.

I've added skype, stun and web-browsing rules to allow skype traffic, but I have 2 Block Proxy rules. 1 block applications and the second one block url category. the policy with url-category is an issue with these 3 rules, created for Skype.

What can be a problem? Maybe some of you can help me.

Hello,

Yes Skype is a beast and cannot be decrypted due to certificate pinning. Its is best not to decrypt Skype traffic and have policies specific to the skype/edge/arr servers so you dont accidentally break decryption for other traffic.

Hope that helps.

I just created a custom url category and added:

Then I created decryption policy and dedicated not to decrypt this traffic.

Thank you very much.
