Backend of my website not responding

when i try to login http://nexprox.ct.ws i get the secure channel offline error from my code backend which shows on the nexprox screen and I have checked my code and forced https redirect on the platform so it seems like a server problem and I could also give link to my github repository so you can review my code for more details GitHub - ZEDON-ARCH/Nexprox: An advanced proxy with integrated tunnel system and powerful server · GitHub
