I had to kill a free service that I absolutely loved due to similar issues.

Couldn’t find a way to monetize, running an old version of node. Upstart vs Systemd, a niche database (rethinkdb) that fell out of favor and upgrading was too painful.

It wasn’t nearly as popular as SSLPing, but it was mine and had a following.

Thanks for writing this note: it’s OK to shut something down if it causes you agony.
