I accidentally locked myself out of my VPS after messing with iptables and blocking SSH access. I was able to reinstall and restore from a backup, but this made me realize I need a better recovery plan for critical situations. I also couldn't log in through my provider's console, which was frustrating. I'm curious about how others deal with this issue. When you get locked out, do you have a standard recovery method? Do you use your provider's console, or do you implement fallback measures like temporary rules, alternate ports, or VPNs?

In tough situations like this, it's also worth considering mounting your OS volume from another machine. After all, it’s just configurations that locked you out.
Honestly, the best fallback is to always have regular snapshots. If I face this issue, I roll back to the latest snapshot without hesitation.
Some VPS providers have direct KVM access available right from your dashboard. It's not affected by iptables, so check if yours has that option. Otherwise, it's all about restoring from backups.
If the provider's console didn't work for you, that's a red flag. Beyond backup solutions, you should figure out why the console access failed. That might help prevent future lockouts.
I was able to access the web console but something weird happened—my password just wasn’t working. It had me frustrated.
Using a serial console or KVM with a single-user mode boot can also really help. Plus, remounting drives or using alternative rescue media can be life-saving.
Exactly, having that access can save a lot of time.
