No connection on my Z8 with a subscription

Hello,

I have a strange problem since this weekend with my Z8.

I can't connect since Saturday to a server I've been subscribed to for a long time either in stalker or XC. Either I'm stuck at 10% or I'm connected but black screen on everything (no VPN installed).

The account works normally on smarters on my shield and other subscriptions i have work on my Z8.

Even weirder, the account works on another formula (in XC of course) in my possession.

I made a reset of the Z8 but without change...

Last thing: on my Z8, I tried a test account on the same server (in XC) and I couldn't connect...

I really don't understand what happened and my reseller too...

If you have a magic idea, I'm listening...

Thanks

I installed the latest beta but no change.

It stucked at 10%, no error; sometimes, it connects but black screen.

Box connected (other subs are working).

mac adress not banned dixit my reseller and it won't explain why it's not connecting on xc or with another account of the same subscribption.

I haven't changed to wifi, the subscription is working on another box on ethernet.

Really weird...

i test my account on another formuler (xc) and it works (same account doesn't work on my Z8 while it worked for years).

I reboot my router 1 million times.

No ipv6.

But if mac adress is blocked, i should connect on xc but no...

In connection sharing with my smartphone, the server works.

I put DMZ on my Z8 but it doesn't change the result.

Another strange thing, I can't put a static ip on the Z8, it loses the connection; only the dhcp is working...

Edit: it seems it's unnecessary to put a static ip in router and z8: only in router ?

I disabled it and no change.

I really don't understand what happened...

I have no error, it stucks at 10% or if it connects, i have a black screen.

I haven't a vpn installed and i always close mol before i shut the box.

You reseller can check that.

New: it works (xc obviously) with a vpn...

So, it seems it's my router which is the guilty but i don't understand what it blocks from now on (i tried firewall off and it's not working)...

Edit 16 november: my ip was banned but my reseller didn't see it. It works fine now.
