unfortunately the blocking of servers is a perpetual battle that plauges almost any publicly listed proxy (vpns, tor, etc). the only way I have found around it is using lesser known/blocked VPNs or residential proxies. both of which probably have subpar data privacy policies, if they even follow them at all.

althought it likely won't help your captcha troubles, I would like to give a huge +1 to mullvad. have been a happy customer for years. in compsrison to proton as a company they have a much more direct/benifitial effect on the web & furthuring users privacy online in my eyes.

Mullvad, IVPN, Proton, AirVPN, or Windscribe are all fine. Depending on how much stock you put into audits the first three are probably a tier above for privacy.

Been using mullvad for at least 3 years, no major problems so far.

Currently I'm not using it so much and my subscription ended 2 months ago, so I'm using the free version of proton which is good enough for the basics of using public wifi.

Proton and Mullvad are the only 2 I'd trust. I suspect that they get similar results.

Proton has gotten a lot better since launch, but it's always a moving target with these things. I really only have issues with some store sites that just don't load with a VPN, which only tells me I don't want to shop there.

WireGuard

Not really answering your question, but there is this open source extensions that automatically solves captchas locally

There are only 2 VPN providers that are worth using IMHO: Proton and Mullvad. All the other VPNs are of questionable quality or their practices make you wonder if you should use them at all (eg logging and keeping logs)

Unfortunately there are websites that try to detect vpns and block you. Fuck those websites. Don't encourage them by giving them eyeballs or money.

AirVPN, but only for its port forwarding to sail the high seas.

ProtonVPN free (paid is still too expensive for me) and Mullvad.

I find that Mullvad is usually blocked more.

For the past 3 or 4 years I was just on ProtonVPN free tier. For past 15 days I am using Mullvad. I really like that you can choose some custom ports for WireGuard, and also the multihop.
What is unfortunate is that I can't generate separate credentials for OpenVPN, like with ProtonVPN. It just uses account ID.

I have also tried IVPN for a week. Nicer UI, but a bit more expensive, sort of. They have variable pricing based on subscription length, and that just makes me dislike them enough to stick with Mullvad. €5/month whether it's 1 month, 6 months, a year or longer.
I don't remember what specifically it was, but I know I also preferred the Mullvad's ToS over IVPN, although both are fine.

I also thought of AirVPN because of port forwarding, but for privacy I'll stick to Mullvad.

What surprised me with Mullvad was the payment processing speed. It only took 4 days from me dropping the envelope with money into mail collection box in Slovakia to me getting the time added. Considering that shipping to Sweden is "3-5 days", they must have just processed that basically immediately.
But perhaps I was just lucky. I'll see the next time.

Depends on use case and the country. I use Mullvad and Riseup VPN and something private (and Tor). Sometimes when a site has Mullvad in Europe blocked, it works when I try one of their servers outside of Europe. In my experience Mullvad is awesome, and you can try it for one month. And Mullvad, the no nonsense VPN provider, has had the same prize since years! (And no discounts like Proton trying to get you sign up for a year or more trying to keep you with Proton).

try to connect to newer servers. solves these kind of issues often but ofc not always.

I don't think there is one. Nord has dedicated IPs you can buy and use so that it's always "your IP" but I'm not sure if they actually solve the blocks and captcha issues.

Nice try FBI.

But seriously... if everyone knew about better options, I think they would already be blocked too :)

Mullvad, haven't had any issues with it. If a site refuses my connection I just change servers until it works, even found a few that work on reddit
