I own a site that was hosted on the firebase, with the option for HTTPS enabled. One day, I decided to host it on a reseller of mine, with a let's encrypt certificate issued to that domain.
In the new devices, there was no strange behavior, but in those who had already accessed the site under https, they reported an error message from ssl. When clearing the cache the situation normalizes.
Is there any way to prevent this SSL error? The new hosting is advantageous to me, but not with ssl error for old users.
