Connection error when log in (Android 7)

After longer break (4 months) today I tried to log in on my tablet (Android 7) but “Connection error. Try again later” appeard. I can log in on my phone but it is not possible on tablet. Have you change minimal requirements for Androids?
Kind regards.

This issue is caused by the fact our SSL provider stopped supporting Android 7, that’s why you are not able to access any site that use Letsencrypt and probably many other ssl certifications.
Here’s the official list of Certificate Compatibility:


Sorry to hear that. Thanks to Marek for figuring this out. Seems that Android 7 is just getting too old (8 years old). If it’s not working for this ssl it seems it will slowly stop working for more and more stuff.
