I'm trying to activate an account on alphanet using a public node. I can't do it via my local node because I run into this problem, which is probably related to this.

So I decided to use a public node that is bootstrapped, like this:

./tezos-client -p PsddFKi32cMJ -A alphanet-node.tzscan.io -P 80 activate account testIdent with scripts/tz1cXy7wuoVoabWgG5kVxG25WdMttKyVv1yr.json -f

However this hangs on

Node is bootstrapped, ready for injecting operations.

For a long time (about half an hour) and then fails with

  Rpc request failed:
     - meth: POST
     - uri: http://alphanet-node.tzscan.io:80/chains/main/blocks/head/helpers/preapply/operations
     - error: Unexpected error 502:

  • A 502 is a "Bad Gateway" error which means the front facing gateway got a bad response from it's backend (the node probably). Perhaps it's also getting the same error as your are seeing on your node? Commented Mar 27, 2019 at 8:52
  • Yep, just use a different node eg chainstack.com/protocols/tezos
