Re: AUR connection issues (EOF/TLS errors)

2604:cac0:a104:d::2 is aur.archlinux.org, though.
So this seems to fall apart at the SSL level
Do you get 301 from

curl -6v http://aur.archlinux.org >/dev/null 

?

And because of my experiences w/ bugs.kde.org: can you maybe actually

curl -6vL http://aur.archlinux.org

Yes, I get the 301.

$ curl -6vL http://aur.archlinux.org
* Host aur.archlinux.org:80 was resolved.

Of perhaps 10 attempts in the last 10 minutes (from Arch FreeBSD and Debian), only one of the above succeeded.

Re: AUR connection issues (EOF/TLS errors)

Because of the intermittency: Does it help to lower the MTU? (1280 or sth. like that)

Doesn't make a difference.

Does here, setting the router's ND MTU to 1280 fixes all Arch properties (and a bunch of previously failing Azure hosted sites as well).

Re: AUR connection issues (EOF/TLS errors)

@stronnag any chance there's a VPN in the route or anything else that might add overhead to the packages?
@maksverver the problem wasn't intermittent for you, was it? Did you contact the accountsupport or ewaller?

No VPN nor any other overhead I can think of.
As you're seeing this, I can also report that setting the ND MTU to the same as the PPPoE MTU (1492) also works.
