'Substrate NPoS Chain Elections Fail

Private NPoS chain using substrate, there are 4 validators, when 1 node goes down, subsequent elections keep on failing even if the node goes back online again. Is it normal behaviour?



Solution 1:[1]

Yes, because one one election fails, it needs to be recovered. There are generally two ways to do this:

submit_emergency_solution, and governance_fallback. The latter is much easier and is made exactly to help test-nets recover easier.

More context and info about why the election is failing should be same as this question.
