I use to be able to send system logs to my email address, prior to the last update. However since this last update, the router no longer sends emails, it fails with the message 'Send Fail'. this occurs with whatever email account I use (gmail.vivaldi, yahoo, proton).

Has anyone using this option in their router experiencing this issue?

I have a NAS drive which also forwards logs to my email and that works. Those email messages are all posted out ok.
