Citrix not connecting in ubuntu 20.04

Cannot connect to. Address family not supported by protocol. Verify your connection settings and try again.

EVerything was working fine. Suddenly, I am getting this error. I deleted the softlink for certificates and recreated. Still not working.

Solution 1:

After fighting for long with this issue, found some link where its mentioned to try disabling ipv6 and it should work. referred this link to disable ipv6 https://itsfoss.com/disable-ipv6-ubuntu-linux/

sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1
sudo sysctl -w net.ipv6.conf.default.disable_ipv6=1
sudo sysctl -w net.ipv6.conf.lo.disable_ipv6=1

though there is mechanism mentioned to do disable ipv6 permanently I preferred to create is a command which i will execute only when i want to connect to citrix. working smoothly for me (with ubuntu 20.04, citrix workspace).
