I get these request on the server daily. This seems to be a port scanner.
[warn] a.a.ActorSystemImpl - Illegal request, responding with status ‘400 Bad Request’: Unsupported HTTP method: HTTP method too long (started with ‘SSTP_DUPLEX_POST’) from 157.245.176.143:47106. Increase akka.http.server.parsing.max-method-length to support HTTP methods with more characters.
[warn] a.a.ActorSystemImpl - Illegal request, responding with status ‘400 Bad Request’: Illegal HTTP message start
Is there a way to get more info from the Akka actor - HTTP method and data being used by the port scanner ?
I see that there are a number of abuse reports from this IP - coming from digitalocean.com
What is the maximum length of a method call in HTTP that is supported by Play/Akka and is there a way change this ?
