I have a python script that is responsible to sign images url to 150 days (v2) with gcs. My problem is the url works just fine but after 4 days when I try to enter the image I get

The request signature we calculated does not match the signature you provided. Check your Google secret key and signing method

    Can you please update your post sharing your script? Have you tried removing the content type while creating the signed URL as suggested [here?](https://github.com/googleapis/google-cloud-node/issues/1976#issuecomment-278762945) Are you using PUT or POST? changing it could help as in [this post](https://github.com/googleapis/google-cloud-node/issues/1976#issuecomment-749231121). Finally, take a look at [this post](https://stackoverflow.com/q/53422663/17544309). – Osvaldo May 20 '22 at 17:00
  • Did you resolve this? I'm also encountering the same error, generating a signature that should last for years but also expires after a few days.. can't pinpoint how many days that is exactly.. – Ognjen Mišić Jan 31 '23 at 22:00
  • No, It just stopped somehow – Ari Feb 01 '23 at 17:03
