Thunderbird *sometimes* fails to send emails
Sometimes TB cannot send the emails but sometimes it indeed can (receiving emails always works fine). I am mainly using Gmail and the email provided by my university and usually either both of them work or both don't. Attached is the error that I am getting. I don't have any antivirus software and my operating system is Gnome Ubuntu 16.04 and TB version is 52.7.0. I am usually connected to internet provided by my university, which uses WPA2&Enterprise encryption and PEAP Authentication if it matters. The problem is very annoying as I cannot even reproduce the error consistently, let alone finding a solution.

Do you have an apple device also getting mail on the device? They have no throttle on their mail package and will continue to login until all available connections are taken. The only time this would be truly visible would be when you send mail as it it about the only time you are involved in the connection process.
Most other software has a throttle that can limit the number of active connections. Thunderbird defaults to 5 and this can be modified in the advanced pane opened from the server settings in account settings.
@Matt no I don't use or own any Mac/Apple devices.
but do you have other devices connecting to that mail account?

My android phone is connected to my gmail account (via the Gmail app) but my university email account is not connected to any device (other than my PC) that I have.
