**Switching to TLS 1.2+ is definitely not the solution.**

Pleased compare your settings to the ones I posted in [After updating website wont come back online - #6 by gerhard](https://meta.discourse.org/t/after-updating-website-wont-come-back-online/128391/6). A rebuild of your Docker container, as mentioned in that post, might help too.
