open ipv6 switch and turn on ipv6 usage of vps
add ipv6 address of google scholar in host file
## google scholar
2404:6800:4008:c06::be scholar.google.com
2404:6800:4008:c06::be scholar.google.com.hk
2404:6800:4008:c06::be scholar.google.com.tw
2401:3800:4001:10::101f scholar.google.cn #www.google.cn
like me, my vps is at india, so I add to the host file
2404:6800:4008:c06::be scholar.google.co.in
the exact domain name of google scholar varies from different contries.
copy the domain name when you access the google scholar.
finally, restart vpn process.
