SSL handshake failed Error code 525, timezone issue?

Hello everyone i have a subdomain which does not resolve because of error 525
What do I need to do? Is it a Timezone issue? Because the errorpage is 2 hours ahead as my local time. Ive read something about that. How do i need to proceed?

You will need to install a valid certificate that covers your subdomain on the origin.

The best way is to change the DNS record for your subdomain to DNS-Only and keep it that way until you have a secure connection, then you can re-enable the proxy.

Hold on, it changed the error after installing my Control Panel. Now its another error:

Invalid SSL certificate Error code 526

I have issued a certificate for *.gerber-web.ch, admin.gerber-web.ch and gerber-web.ch

The Link with error is the admin.gerber-web.ch

I can see that you have not changed the record to DNS-Only yet.

Okay i changed it now, no difference…

The certificate does not cover admin.gerber-web.ch, only these names:

DNS Name: gerber-web.ch
DNS Name: shop.gerber-web.ch
DNS Name: social.gerber-web.ch
DNS Name: support.gerber-web.ch
DNS Name: www.gerber-web.ch

You will need to fix that.

Thats strange i explicitly wrote admin.gerber-web.ch in cloudflare down for the certificate. Ill make an additional certificate for only admin.gerber-web.ch then it will work i hope.

Herer as you can see:
