Mail reception failure with Outlook in POP

Hello,
for a few months now, my Outlook mail account set up as POP has not been able to receive emails randomly.

I have several email accounts, all of which fail to receive emails when the issue occurs, even though 5 minutes prior there was no problem receiving emails.
Closing Outlook does not resolve the issue because when I reopen it, the reception remains blocked.
Only restarting the computer resolves the situation... until the next blockage.

I installed Thunderbird as POP to see if it behaved the same during the Outlook blocking periods, and Thunderbird does receive emails when Outlook cannot.
I have enabled logging for troubleshooting in Outlook to detect the issue, but it doesn't tell me much, except that there is an error: 0x8004010f|FAIL to connect to the POP server.
Everything is set up correctly in Outlook for the POP server because it works perfectly under normal conditions until the random issue appears when an email reception is triggered.

I would like to try stopping the ongoing Outlook processes during a blockage, but aside from Outlook.exe (which does not resolve the email reception block when reopening Outlook), I do not see any other processes running.

I have uninstalled and reinstalled Outlook 2024 (Office 2024), reconfigured my mailboxes, and the problem persists.
And the issue also occurs randomly on another computer, for the same email accounts using Outlook 2010.

How can I see in Outlook what is blocking, and if restarting the computer no longer blocks it for a very random time (logging off is not effective, only restarting allows Outlook to be unblocked, but I would like to know if we can avoid this by closing certain processes).

Any ideas?
Similar cases?
Thank you in advance for your responses.
