On a recently launched Netlify website, we are seeing intermittent ERR_SSL_PROTOCOL_ERROR in Chrome.
Intermittent here means it comes and goes within 10 minutes on a single machine+browser, but can come back as a problem a day or two later; about 1 in 3 accesses is problematic. We’ve observed the issue across multiple machines, across Europe.
Our setup is:
- DNS hosted by DNSimple, DNS for website changed to point to Netlify domain within last week
- Multi-domain Lets-Encrypt certificate with root domain and www subdomain
- www subdomain redirected to root domain
Example problem request:
Har file available on request.
Any ideas as to what the problem might be?
There appear to be reports of similar issues on the forum, but no suggestions for resolution, other than wait and it went away.
