Hi just today I started to get this error when trying to do anything on devnet:
Error: unable to confirm transaction. This can happen in situations such as transaction expiration and insufficient fee-payer funds
This includes just doing:
solana airdrop 1
on the terminal.
Some things work, e.g. solana balance shows a sensible value, but I can't seem to do anything with transactions. The airdrop doesn't go through, it just sits there for a while and then I get that error.
Any suggestions?
