Any workarounds? Manually download repository? Hosting company is running Trusty which I don’t have much control over. 
can you use ipv6? i thought about making a ipv6 only (AAAA) direct record to git.tt-rss.org since this wouldn’t expose origin ipv4 IP.
Yes, it looks like ipv6 is enabled on the host.
alternatively maybe a better idea would be setting up an automatic mirror somewhere like gitlab; however i’m not sure how friendly those services are to clients with older OSes.
apparently i have a gitlab account

someone with a vintage OS check if it works for you
I just tried and got a 403 error. I was able to clone one of my own repos from gitlab to my web host, so in principle it should work.
i poked at project settings a bit and cloning over https works for me now, without authentication.
