I get this output:

Not sure if this is an issue with this library or the ECC library.

@kanishkdudeja yeah me too. Tried more than 15+ tokens and their corresponding keys etc didn't get a result. Then switched to google's node.js library and it worked.

Yep, same here. I keep getting:

Hi,

Please look at the other open issues before creating a new one. This is the same as #12 and should be resolved by #13, but you can fix this already by correctly using the regular base 64 encoding (MIME spec) instead of the URL-safe variant.
BCXxO8IhPp_PVjnfx7TugJA3gYdQd3jZUzfcinsjiLjtCL_uJf_2Y9fK8HYkAp2ot6FXs5q7ZFOzdiNlttThpdA= is clearly Base64 URL safe encoded and so does your auth tokens.

Hi Minishlink,
I am using https://github.com/Minishlink/web-push-php-example to send push using VAPID.
In 50% cases above code is working fine but in other 50% cases i am getting error. Please find error message below.

I am using you latest branch from git.
My src/Encryption.php file already using
$userPublicKey = Base64Url::decode($userPublicKey);
$userAuthToken = Base64Url::decode($userAuthToken);

Please find 2 endpoint, key and token below that is throwing error.

Hi Spomky,
Your solution is "Closing as it looks like the issue came from a double encoding.", But at what point double encoding is happening ( Link : phpecc/phpecc#235)?
If double encoding is the issue, then why i am getting this issue in 50% cases?

[Minishlink]

Hello @akhilesh-kk2, can you try with v4 (or v3)? If the problem is still there please open a new issue (I totally forgot you commented on this one)

[akhilesh-kk2]

Hello Minishlink,
I tried to send push using V4, but code throwing new error messages. Please find error message below.
