openconnect nexthop has invalid gateway and invalid values for route get request

I am trying to connect to my university network with openconnect. When I do, it asks for my credentials and then outputs the following: POST university_url Got CONNECT response: HTTP/1.1 200 OK CSTP connected. DPD 30, Keepalive 20 Connected as my.ip.v4.address, using SSL, with DTLS in progress Established DTLS connection (using GnuTLS). Ciphersuite (DTLS1.2)-(ECDHE-RSA)-(AES-256-GCM). Error: Nexthop has invalid gateway. Error: ipv4: Invalid values in header for route get request. on arch linux. Cisco anyconnect works fine on a ubuntu vm on the very same machine (clumsy workaround), however I would rather resolve the cause of the issue. This is unfortunately beyond my skilllevel. Any help would be much appreciated.
