Hello,
I just installed avast on my computer and since my connection vpn does not start anymore! After some research I found that it was the mail agent that was blocking the connection and especially the email scan POP3 and IMAP4! Normal my vpn goes through port 465! When I uncheck the box pop 3 it works!
I tried to add exceptions via Settings / Exceptions / but it did not work, I tried to enter the process, ip, ip and port but nothing is done! I confess I do not understand how I can tell avast not to block my vpn without unchecking the pop 3 Imap4 box.
Do you have an idea ?
