Something went wrong: 400: - { "errors": [ { "msg": "Something went wrong" } ] }

I have a wallet which is eligable for the dydx airdrop but everytime i go to sign the transaction with MM I get the the error message
“Something went wrong: 400: - { “errors”: [ { “msg”: “Something went wrong” } ] }”
From the dydx site. I have seen this happen on another site in the past but i think i just carried on with my life but i’m worried what opportunities this will cause me to miss out on going forward.
I have crated a second ETH wallet address in MM and connected to the site fine with that. I’m worrid it’s something to do with the address and not so much MM.
Has anyone experienced this before?
