SSL Certificate error


[Failed (code #4)] SSL certificate error: Let’s Encrypt returned an unknown error. Please try again later.

Other Information

I am trying to request a new SSL certificate but after a few tries, I still get this same error. Please advise. Thank you!

I checked our logs and as far as I can tell, it’s caused by an issue at Let’s Encrypt. The error message is quite weird and I can’t think of another explanation.

Can you please try again tomorrow?


Yes I will try again tomorrow. Thank you.

I see the exact same error on my account. Renewing my existing SSL certificates do not work. I have 7 days until my SSL certificates expire. Will try again tomorrow but if you want to, do have a look at logs for my account as well.

There seem to be major issues with let’s encrypt ATM according to So the problem is definitely there and not at Infinityfree.

The problem is solved and I managed to renew one SSL certificate just now.
