What LCP TermReq after IPCP ConfReq id=0x2 <addr 0.0.0.0> <ms-dns... means?

Short snippet:

Sep 16 01:39:13 raspberrypi pppd[581]: rcvd [IPCP ConfRej id=0x1 <compress VJ 0f 01>]
Sep 16 01:39:13 raspberrypi pppd[581]: sent [IPCP ConfReq id=0x2 <addr 0.0.0.0> <ms-dns1 0.0.0.0> <ms-dns2 0.0.0.0>]

Does it mean that server does not like any client OS settings or some error on modem part?

    It's been a *really* long time since I did anything with PPP, but I believe this means your `raspberrypi` PPP client is asking the far end to assign an IP address, and the far end can't or won't, so it terminates the connection. The far end would typically have a pool of addresses configured for dynamic assignment, and possibly also static assignments for known clients (typically based on login name). – James Sneeringer Sep 16 '20 at 01:12
  • Check the logs on the remote PPP server. – Michael Hampton Sep 16 '20 at 01:14
