Please:

• 👍 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

I'm sure this isn't the comment you were hoping or expecting to see, but I just had to let you know that I've been tearing my hair out over the past 24 hours trying to troubleshoot this same error (also using ProtonVPN btw and also on a NAS (asustor), could be relevant) but as I'm new to all things docker so I expected that I was doing something wrong as I've never spun up a gluetun container before!

I'm so happy right now, using v3.38 is indeed working! You've saved the day for me tbh.

I am having this same issue! Also ruining on a synology nas.

[qdm12]

This should be fixed by ef6874f let me know.
Related to #2256

[Shadex9]

I can confirm it is working again. @qdm12 Thanks for the quick fix much appreciated.
