Kaspersky antivirus blocks access to my encrypted webmail

[yellowsub]

This is happening from today, it must have been the latest antivirus update because for the last year I did not have any problems.

When I access my webmail (Posteo.de) and I click on the Inbox or any other folder I get the message "Sever error! (request has been forbidden by antivirus)", it is impossible to read anything.

I don´t know if this is relevant or not but the inbox is fully encrypted at server level.

I solved it by pausing the antivirus and I have been able to access the Inbox after this, it confirms that Kaspersky antivirus is at fault here. I am using the free version.

Hello yellowsub.
What version of Kaspersky Free are you using?

First, please try to disable the Encrypted connections scanning: open Kaspersky > Settings > Additional > Network > "Do not scan encrypted connections".
If the error persist, add the site to the exclusions list: https://support.kaspersky.com/13971

It is now working with Kaspersky on. If the error happens again I will update the thread but I am going to add the email URL to the exclusion list.

 I prefer not to have my email messages scanned. We already have built-in antivirus on the server.
