After the 1909 update, I'm facing a peculiar problem. Outlook and other apps (Adobe Cloud and Filezilla, for example) cannot connect to the web after a while once the PC starts. Outlooks starts giving a 0x80042018 error while other apps give a "cannot connect to the server" type of error messages. However, web browsing is fine.

I have tried putting the firewall and anti-virus (both Microsoft Windows) off but the problem persists.

Anybody else faced such an issue and have a solution?
