Palmr unable to Download shared file due to 'ERR_OSSL_WRONG_FINAL_BLOCK_LENGTH' error

[gh2023-aesun]

I installed Palmr v3.1.8-beta yesterday using the helper script with the default settings.  I am able to login, upload files to share, but when I try the share link the download fails.

Typing the share link into a browser yields:

When I click on the download icon I get these responses:

In Brave the error message is:

In Firefox the redacted error message is:

Looks like there’s a problem with this site

http://xxx.xxx.xxx.xxx:xxxx/api/filesystem/download/xxx might have a temporary problem or it could have moved.

Error code: 500 Internal Server Error

    The site could be temporarily unavailable or too busy. Try again in a few moments.

The on boot journal file does not seem to reveal anything catastrophic:

Looks like some type of block length error.

I've tried different browsers on different devices, clearing cache, deleting cookies, but all with the same result.

Any thoughts on how to proceed?

Thx

Report it to their repo, this is not a script issue

[gh2023-aesun]

I see on the Palmr github that the last commit was on August 1st, 2025:

The Palmr Community Helper Script was released on August 7th, 2025.

Do you have a successful installation of the Palmr v3.1.8-beta post the August 1st, 2025 commit?

If so, then maybe it's something with my environment setup.

If not, what version do you have installed that works and can I modify the Helper Script to install that version?

I will also post a bug report on Palmr's github.

Thx

I resolved my issue by trying to install the prior version of Palmr.  Here is what I did.

I cloned the installation script, changed the two instances of latest to v3.1.7-beta and ran it. Once the script completed I had an instance of Palmr that performed as expected, with no download issues.

I'm not sure if this the correct way to downgrade a software install as  ✔️ Deployed: Palmr (3.1.8-beta) was printed to the script log and the Palmr GUI also displayed
. 

However, it resolved my issue.

I also filed a bug report at the Palmr github here.

🔧 Installation note for v3.2.0-beta
I ran into an issue caused by changes in the folder structure introduced in recent updates. Uploaded files were no longer being found, likely due to outdated paths.
To fix it, I completely removed the previous installation and did a clean setup using version v3.2.0-beta. Everything is working fine now.
👉 If you're facing similar errors, I recommend starting fresh with the latest version.
Big thanks to the maintainers for their great work
