Origin crashes - no connection to the servers

[Dissonance1983]

For the last 3 days, Origin (PC) has crashed 10 times. The error is "no connection to server". Without this connection, I cannot start ME3. Then it started to work but every mission I got crash of Origin and ME reports that the game will be closed.

Traceroute and DNS are OK, stable and up to 150ms.

Most surprising - they close the support line. Best service!

Do you run Origin as Administrator?

Did you cleared your Origin cache.

Are you on a private or a public (university) network?
Does your EA Account email address or username contain special characters?

Restart your router in this way:
Pull the power plug > wait 5 minutes > return the power plug
If that not helps, shut down your Windows firewall and disable the real-time scanner of your antivirus software.. (just for testing purpose, don't forget to activate the firewall and the antivirus software later on.)
Should it work after you disabled the firewall, here is a description how to allow a program to communicate through the firewall.

This ports must be open on your Router:
Origin Ports
TCP: 80; 443; 9960-9969; 1024-1124; 3216; 18000; 18120; 18060; 27900; 28910; 29900
UDP: 1024-1124; 18000; 29900
Me3 Port
Port 3659

Clearing your DNS cache. or testing a google DNS could also help.

The support lines are open, just at reduced times.

@holger1405 Thank you. I have already completed the game by restarting from save each time.
