mail.com and 123-reg servers inconsistent connection on Thunderbird

I have been using Thunderbird for mail for a couple of years with Wondonws 10 but now am having trouble with it. After a restart of the PC everything works. I can send and recieve email on all four accounts I have set up on TB (two IMAP and two POP), but after about half an hour things start to go wrong. I will not be able to send email via one or all of the servers or receive email. I get a timeout message. All the account settings are correct. I have tried all sorts of things like turning off mail fetching on the IMAP accounts, and someone suggested Chrome was interfering with something so that got uninstalled. I've checked connections to the ISP and that's all fine. But I am now at a loss at what to do. I'd really like to continue with TB but losing patience now. Here ios the troubleshooting readout:

I have been using Thunderbird for mail for a couple of years with Wondonws 10 but now am having trouble with it. After a restart of the PC everything works. I can send and recieve email on all four accounts I have set up on TB (two IMAP and two POP), but after about half an hour things start to go wrong. I will not be able to send email via one or all of the servers or receive email. I get a timeout message. All the account settings are correct. I have tried all sorts of things like turning off mail fetching on the IMAP accounts, and someone suggested Chrome was interfering with something so that got uninstalled. I've checked connections to the ISP and that's all fine. But I am now at a loss at what to do. I'd really like to continue with TB but losing patience now.

Chosen solution

An update. I thought that removing one of the IMAP accounts from Thunderbird had solved this but it didn't. However, I did eventually work out what was causing the issue. My motherboard is made by Gigabyte and bundled with drivers is an app called Lan Optimiser. Lan Optimiser manages internet connections to prioritise certain uses and somehow this was interfering with connections to the email servers. Uninstalling the app (which isn't required for the motherboard LAN chip to operate) solved this issue.

How often do you check for new mail? Some email providers limit the time interval for this. Checking every 10 min should be fine. Checking more often can be problematic.

Thanks for the suggestion. On the IMAP accounts I don't check at all because the server is supposed to push them to the client(so I understand anyway). THe two POP3 accounts were set more frequently than 10 minites, so I have changed that and I guess we will see if that helps for them.

... it doesn't help. I still get failed connections on the POP3 when sending after a few minutes up time
