Ok problem is in certificate. I used ssl checker and got error so now I know what to do

The certificate is not trusted in all web browsers. You may need to install an Intermediate/chain certificate to link it to a trusted root certificate. Learn more about this error. You can fix this by following Comodo's Certificate Installation Instructions for your server platform (use these instructions for InstantSSL). Pay attention to the parts about Intermediate certificates.


Is your system date/time ok (Both server and phone)? The error code states "DATE INVALID"

It could also be an antivirus which thinks something is wrong with your certificate and somehow triggers a wrong error message

  • Yes I know that date must be same. also antivirus can cause this problem. Dates are same. It works from any pc. But I have problem from mobile devices.
