Hi,
My name is Lem. 
    
I tried to use curl to check EPP and got in log:
[26/Apr/2020:15:25:36 +0600] 192.168.0.1 (process:16846)
      [sessionID 61959] Client connected
      [26/Apr/2020:15:25:36 +0600] 192.168.0.1 (process:16846)
      [sessionID 61959] Corba call (epp-cmd hello)
      [26/Apr/2020:15:25:36 +0600] 192.168.0.1 (process:16846)
      [sessionID 61959] Corba call ok
      [26/Apr/2020:15:25:36 +0600] 192.168.0.1 (process:16846)
        [sessionID 61959] Invalid epp frame length (1347375952 bytes)

      [sessionID 61959] Session ended
    
Please help me. What do I wrong?
