ProtonVPN

What are you using to run the container

docker-compose

What is the version of Gluetun

What's the problem 🤔

Tried to run:

docker run --rm -v /mnt/cache/appdata/gluetun:/gluetun ghcr.io/qdm12/gluetun update -enduser -providers protonvpn

But get a Bad Request Error

@qdm12 is more or less the only maintainer of this project and works on it in his free time. Please:

• do not ask for updates, be patient
• :+1: the issue to show your support instead of commenting @qdm12 usually checks issues at least once a week, if this is a new urgent bug, revert to an older tagged container image

[SerhiyRomanov]

I'm faced the same issue

[harrytheeskimo]

Same issue here also

[leosuncin]

How I "fixed it":

1. Stop the container
2. Remove servers.json file
3. Start the container again

[dot-i]

I don't think that's a fix 😉 I think that makes it simply fall back to its default internal servers.json from the time the container was built.

[astrdev]

same here

[Nebula-0-System]

i'm dealing with this same issue and it's preventing me getting my service up and running on my server.

[RChesterton]

Same issue here

docker run --rm -v /mnt/user/appdata/gluetun:/gluetun qmcgaw/gluetun update -enduser -providers protonvpn 2025-08-04T22:58:48Z INFO merging by most recent 20776 hardcoded servers and 20776 servers read from /gluetun/servers.json 2025-08-04T22:58:48Z INFO updating Protonvpn servers... 2025-08-04T22:58:48Z ERROR updating server information: getting servers: HTTP status code not OK: 400 400 Bad Request 2025-08-04T22:58:48Z INFO Shutdown successful

Additionally, the "automatic" update period seems to just hang and never update servers.json

[jm1tchell]

This just happened to me as well. In my case, the Wireguard configuration had expired. Created a new config (didn't notice the "extend" button in Proton, that might work too) and updated the key for Gluetun and all is well again.

Something to check.

Interesting. Will check this tomorrow, but the VPN is able to connect/reconnect fine, so I don’t think that’s the issue for me.

Are you sure the server list is updating correctly? I ask as I found out that Proton have retired their public API, which most things were using to pull this data.

[jm1tchell]

@RChesterton Maybe it isn't the solution here, but I thought it might be worth checking.

Just re-ran the update command and still get the 400 error, so I guess my problem was the token and this one still exists. Sorry for the wild goose chase.

[alanstrok]

No update regarding this ?

[RomainJM]

Has anyone found a workaround to this problem?

[RChesterton]

Has anyone found a workaround to this problem?

Pretty sure there isn’t one until/unless Proton make an API available.

[SerhiyRomanov]

you can follow some discussions there https://github.com/qdm12/gluetun/pull/2864

[JoshuaVandaele]

Has anyone found a workaround to this problem?

I have simply switched to using VPN_TYPE=wireguard and VPN_SERVICE_PROVIDER=custom using ProtonVPN's wireguard configurations that can be obtained from their download page, which has been working flawlessly for me.

[joshbuker]

It looks like for me this was a case of the ProtonVPN wireguard config expiring. Extending it from the download page seems to have fixed it.

I tried this using a server that was newly added by Proton, but got an error saying that servers should be from one of the perfect providers.

[JuniperMS]

Is this still an issue because I don't see any failures in my logs.

This just happened to me as well. In my case, the Wireguard configuration had expired. Created a new config (didn't notice the "extend" button in Proton, that might work too) and updated the key for Gluetun and all is well again.

Something to check.

This fixed the issue I was seeing, thanks!

[1337SereniTyx3]

Hey @qdm12 , there is an updated list of ProtonVIP IPs at https://github.com/tn3w/ProtonVPN-IPs. I am not a developer, but maybe there is a way to import this into gluetun while we wait for the Proton team to allow the API connection again?

[oliversalzburg]

Proposed Workaround

1. Open DevTools to ensure browser network traffic is captured.

2. Go to ProtonVPN web portal to create a new Wireguard configuration.

3. Check the network tab for the request that pulled the server list. Either copy the response JSON straight to a file, or use the "Copy as curl" options to repeat the request in the shell with curl. We assume the filename to be protonvpn-servers.json.

4. Process the file with jq:

   jq '

    		$ls.Servers[] | {

5. Merge the result into your gluetun servers.json, and don't forget to bump the timestamp.

[F1zzyD]

Yes, this is still an issue. I tried extending my config in Proton and adding HEALTH_RESTART_VPN=off in my compose file. Gluetun is borked and will not let me make any connections.

5. Merge the result into your gluetun servers.json, and don't forget to bump the timestamp.

Thank you. I was able to get a list of updated wireguard servers and sort it with jq. I have three follow-ups:

1. How do I merge this with gluetun's servers.json? Is it a simple copy and paste or something else involved?
2. Does bumping the "timestamp" mean increasing the counter by 1? My current timestamp value is 1722515320. Do I just make it 1722515321?
3. Can this be used also to get a list of openvpn server entries? If so could you please explain how to pull them?

[oliversalzburg]

@1337SereniTyx3

1. Copy & paste will do fine. I removed all providers which I don't use from the file first. Then I just replaced the entire servers section of protonvpn.
2. Increasing by 1 should do fine, but it's a UNIX timestamp (in seconds) if you want to be precise. I used 1761381398. The servers.json is also hardcoded into gluetun. When it finds entries with a more recent timestamp in the file on disk, it will replace the hardcoded values with the newer ones. This will show in the log with a distinct message on startup.
3. I've been wondering about the openvpn servers myself, but I haven't looked into that at all yet. I assume the process could be similar. The API route that retrieves the VPN servers is https://account.proton.me/api/vpn/logicals, and this response is used for both wireguard and openvpn config generation. So it probably boils down to writing the correct jq transform, but it looks to me like you'll ultimately be using the same servers regardless of the protocol.

Thanks for confirming :)

[JuniperMS]

@qdm12 is there any plans to change how the Proton VPN server list is updated?

[qdm12]

Try image with tag :pr-2878. It has updated servers data. It will get merged in the master branch (:latest image) in the coming few days.

[JuniperMS]

Seems to have an issue, @qdm12. If I move to :latest the container fires up.
