As I mentioned within previous article on this subject – none of the supposed helpful resolutions to this problem have worked. Amazon Lightsail console works perfectly fine under Debian 10 “buster” but provides this error code after updating to Debian 11 “bullseye”.
I currently have no way to download software to try and login remotely.
Solutions below haven’t worked to resolve problem. I have tried several times past 30 days to get things working. Each time I revert back to Debian 10 “buster” from an Amazon Snapshot Instance.
Solution below not relevant – server time is set properly.
Same problem no one even bothered to answer with steps to try to solve it.
This thread doesn’t give enough instructions as to how to implement solution. And it isn’t Debian specific.
Haven’t tried hassling with this set of instructions to possibly resolve Lightsail Secure Console login error.
