Im having an issue with HA and SSL. I use my Asus router to handle my lets encrypt cert. It just expired yesterday so I created a new one with the router and exported the cert and key files.
Heres the problem, I have no issuse with the certs on my Synology and everything reports ok (getting a green lock). Using the exact same certs (as I have done many times before) HA refuses to connect securely. I have cleared cache etc but continue to get an NET::ERR_CERT_DATE_INVALID error.
If I check the details the date its says it expires yesterday.
somehow your certificate did not get renew. So you are still running the old cert which expired a day before. Either you renewed the certs or delete the old certs and create a new one so you can have it back running.
I just renew them manually through my router. I also thought it didnt renew, however when I load them into my Synology they load no problem with an expiry date 3 months from now.
My Asus router has a lets encrypt feature that uses my DDNS. It usualy works really well. I generate the certs on the router and export the 2 files. I then import them to my NAS and copy them over to my HA. With the ports forwarded I get an encrypted connection (Green lock symbol) with chrome, firefox etc.
The current certs are working as normal on my NAS, indicating that the certs are fine. When I inspect the certs the dates are correct and are not due to be updatd for another 3 months.
When I open my HA using my DDNS the certs are stuck on the od date and get the warning that the dates are incorrect. Its really strange
I ended up installing the Nginx Proxy Manager add-on in Home Assistant. I let that handle the certs etc. Its so much easier and auto updates the certs etc.
