PPoE-client can not connect

Good day!
I have a problem with RB750 RouterOS v 4.11
PPPoE-client (on MikroTik) can not connect to my internet provider’s PPPoE server.
PPPoE log:

13:15:51 pppoe,ppp,info fttb10568: initializing…

But my PC with Windows 7 can connetc to this provider’s PPPoE server!
Analyzing PADI-packet from MikroTik and from Windows I noticed thet they are different:

MikroTik, broadcast 34915 (pppoe-discovery)
1109 0000 000c 0103 0004 0000 0001 0101 …
0000

Windows broadcast 34915 (pppoe-discovery)

1109 0000 0014 0101 0000 0103 000c 0700 …
0000 0000 0000 0c00 0000 0000 0000 0000 …
0000 5405 e0ff 0003 ff70 14eb 001d ..T…p…

I think that in PADI packet from Windows at first tag Service-Name, then Host-Uniq. From MikroTik vice versaб and provider’s PPPoE server does not understand this.
My be I mistaken and problem in another?
I maked ticket, but may be sombody here know what to do?:slight_smile:

Please post the output of ‘/interface pppoe-client export’ here. Remember to remove your ISP’s password.

Tip: Do not enter a service name in the RouterOS pppoe client settings if your ISP do not require you to.
