Error contacting the remote site: Payload error – Syntax error

Does anyone know what the solution is?
I have plugin (WP Remote Users Sync)
I’m tired of trying. I have 3 sites and 2 work fine and the last site always gives this error (Error contacting the remote site: Payload error – Syntax error)
in Activity Logs {
