Schannel this is a windows operating system engine, which makes the communication with the e-mail server.
Microsoft outlook will use it and even other software email clients.

Schannel includes a portion of e-mail client communication protocols, them be hidden within the operating system files, and they never get updated.



Microsoft gave the final strike to windows XP by all their email client communication protocols, to not be supported (be accepted) due the recent configuration of all Linux email servers at  June 2020.


Schannel Error 40 and 70  (as combination) by a large proximity, this translates that your ISP this has technical issues,  that could cause networking packets corruption.
Another way this to verify such ISP related issue, this is having problems also with on-line gaming at the same period of time =  Game crash and or poor connection with the game server.
