Renew certificate 2017 edition

Today I used my trusty post Resolve certificate error for Synology Diskstation part 3 of 4 again to renew my certificate. The site is still alive, is still free and still works. They even send me a reminder 2 weeks in advanced of the certificate expiring.

Uploading the certificate caused my browser to throw errors. The certificate was not trusted. Not happy 😦

There was some turbulence since last autumn. I totally mist this.

I need another (free) SSL source.

After some searching I ended up using since I could verify my domain by adding a TXT-record. Other sites needed me to host files or open ftp to them with username and password 😯

To verify my domain using a TXT-record I noticed the google support page was not providing the right solution. The DNS entry should have _acme_challenge for the Host name:

Type Host Value TTL
TXT-Record _acme_challenge R4nD0m57R1n9 1 min

The provided certificate is valid for 90 days. Safari trusts this CA and the certificate. I’m happy again. 🙂
