Hello ChipMixer,
From last 1-month after transferring BTC to your wallet when ever we try to restore session to withdraw our BTC your page goes dead and we always get error "Server internal error".
This error pop only after we transfer the BTC to your wallet, if we don't send BTC and we try to restore session is work perfectly.
SO KINDLY TELL US WHAT'S THE CATCH.
Have you tried accessing their website via Tor on their onion address? (

I've occasionally had problems accessing their clearnet address as well, but their onion address seems to be unaffected by whatever is causing this occasional issue.
