constant 'curl: (56) Recv failure' attempting to update with aurutils

I've been trying to update my AUR pkgs for a couple weeks and keep getting a 'curl: (56) Recv failure: Connection reset by peer' error when aurutils is querying for updated pgkbuilds. At first it only happened around half the time but even when it managed to curl successfully it would later eventually fail while fetching the updated pkgbuilds with git, I left it for a couple days and tried again and have almost exclusively received curl 56 failures since. I've tried a few different things on two different systems every couple days attempting to resolve the issue (or wait for it to fix itself) with little change in behavior until i just tried connecting through my phone's data as a hotspot and it immediately worked with no issues (at least once anyway, i tried to run it again a few minutes later to sanity check but a snow storm rolled in and my data's not connecting to anything right now), so it seems to be a networking problem between my home network and the AUR rather than any configuration issue with my systems.

What I don't know is whether that issue is with my network configuration or if my IP is being limited by the AUR in some way, it doesn't seem to be an outright IP ban since i can still browse the aur and other archlinux pages just fine but i don't know if there's other kinds of IP restrictions that could be in place. While researching i found that people with satellite internet may have issues due to carrier-grade NAT assigning the same IP to multiple users, but i've had this service since November and haven't had any issues updating aur pkgs until the last couple weeks, and the only thing i've changed in my network since it was setup was configuring my router to use Google's DNS servers which i already tried removing to no effect. Disabling the firewall also has no effect and there's not much else relevant i can even configure with how limited this thing is.

Is there anything i can do to determine if this is something misconfigured on my end, the way my ISP is configured, or some restriction on my IP by arch's servers? And if it's a problem with my ISP is there anything i can do about it aside from a VPN? Or is it possible something else is going on entirely?

Can you reach aur.archlinux.org w/ openssl, https://bbs.archlinux.org/viewtopic.php … 5#p2269705 ?

I don't really know what the results are supposed to look like but it seems like it worked to me

$ openssl s_client aur.archlinux.org:443
