Network problems occured as soon as Zemax OpticStudio 20.2.1 Premium was launched, reflected in not being able to access the internet or the default gateway (timeout).
And within 1 minute after exiting OpticStudio, network was recovered and everything turned normal.
Had tried for 5 times, and things above were reproduced 100%.
Please solve the strange problem as soon as possible. Thank you!
Hello!
We haven't seen other reports of this, but you might try installing 20.2.2 just to force a refresh of the files and licensing runtime that comes with it.

If that doesn;t help I wonder if you have antivirus /security software that is blocking part of OPticstudio's license service or something? What antivirus do you use?
thanks and Best regards,
