Can't acces Trello

Question

Hi, I can't access Trello through any of my browsers (tried chrome, firefox and edge) and through the desktop app. BUT: everything works when I use my phone as a hotspot (with data enbaled and wifi disabled) and I get internet on my computer that way. So I suppose the problem is with the network I use at home. How do I solve this?

I get this in chrome:

(to be exact the same thing but in polish - this is a picture found on the web saying the same thing)

In firefox I get this error:
SSL_ERROR_BAD_CERT_DOMAIN

And in Edge I get this:
DLG_FLAGS_SEC_CERT_CN_INVALID

In Trello desktop app:
"Your connection is not private. The certificate fort trello.com is invalid. Please proceed with caution. "
(but when I try to proceed I still can't access it).

Hi,

Make sur that Windows certificate store is up to date.

Certificat "Digicert Global Root CA" must be present in the librairy and not expired.

Thanks for your response. I understand - but Trello is THE ONLY site I have that problem with for like 2 months or so - it makes me think it is (at least to a certain degree) specific. By the way I did search it (the name of the error) and tried some solutions but the problem persists (however i din't try all of them yet). I would also like to stress that the problem is not browser specific.

edit: I'll check the link, thanks
