Unfortunately, my Opera Browser VPN on Debian 10 has same mobile version(Android) problem.
By the way I hope this issue will be fix as soon as possible.
God bless us

@leocg No I didn't try with other ISPs I'm using TCI and MCI services
Opera VPN will connect by 1.1.1.1
This video can prove Opera VPNs blocked in Iran (definitely by Islamic regime) if still it is working on other ISPs they will close very soon internet.ir has page asked the users report all VPNs and proxies!, etc

@mehradmansouri some of them has free plan

@amina2k 1.1.1.1 is name of application from cloudflare you can wrap opera with that but it has two option one option is free than it can wrap dns free and other option is wrap+ it is limited, you can only wrap 10GB bandwidth traffic
What is 1.1.1.1?

I read a news Mozilla want add vpn to Firefox it seemed they used cloudflare technology instead of vpn!. I'd love Opera with free VPN but Islamic regime broke my heart

For Desktop version you can use opera add-on vpns

@mehradmansouri I'm pretty sure, if you connect with other VPNs or app such as 1.1.1.1 you can connect without any problem, Islamic regime blocked Opera VPNs unfortunately moreover I don't think Opera want change VPNs address because they mentioned already the VPNs probably can encounter with problems in countries like Iran

@vr51 I'd same problem It clearly show us Opera VPNs blocked by Iranian Regime ISPs
