check with your web host to possible IP block or the log files to see why page isnt being served
OK I investigated a little and here is my result (however it's still not working)
i found url how to check callback log directly on the blockchain:
https://api.blockchain.info/v2/receive/callback_log?callback=http-urlencoded_my_website/callback.php?parameters&key=my-api-key
the log shown me something like that:
can some1 help me with that?

first you said callback wasnt happening.
if it is happening, but not doing what you want, try printing out mysql error. maybe its not connecting properly to your DB.
Just keep printing out log variables and see at what point it breaks

to simplify my asnwer..
if i am calling callback url manually via browser with ? & & parameters, it works , so callback url is correct, script is doing everything correctly..
but: when i receive payment to my generated address , blockchain does not triggers the callback so the callback url is not called
Right, so what I am saying is that if the url is not called then you can't blame the script that is (not) being called.
You need to look into why blockchain isn't doing the callback.
exactly.. i agree with you...
80% of code mentioned in the main post is copy/paste from blockchain API documentation.
the reason i published here my non-secret part of php code is, that maybe somebody can find the reason why blockchain not calling the callback url.
and sorry for my english

but did you try simplifying script to get write to a text file?
Did it work or not
Did it work or not
as i mentioned - my first callback wrote only date + txhash to the text file.. so yes, i debugged as you suggested...
also callback url is a live php file
manually worked, but when i received satoshis to my blockchain wallet generated with the first script (with callback url included) - this event was never fired..

maybe it is using POST not GET?
again i recommend just confirm the call works with simple text log.
then you can try
parsing all parameters POST or GET to see what is passed, maybe some variables are misnamed etc

i already tested that... and manually: works , blockchain -> no success...
blockchain API using $_GET , that's why i used GET
i think, my callback URL is not in good format or something meesed up in this part of code

if the callback isn't called then not a prob with your code.
Simplify your callback script to do a simple debug log in a text file
and see if it gets called or not.
if it doesnt get called, then problem is on blockchain side

I already made a debug directly in the callback php file.. these lines:
Code:
$gt='CALLBACK CALLED - TXID:'.$transaction_hash.' VALUE '.$value_in_satoshi.' SCRT:'.$scrtt.' CONFIRMS:'.$_GET['confirmations'];
$qry= "INSERT INTO DEBUG (TE) VALUES ('{$gt}')";
mysqli_query($conn,$qry);
$qry= "INSERT INTO DEBUG (TE) VALUES ('{$gt}')";
mysqli_query($conn,$qry);
are adding basic info about transaction to my mysqli database..
but there are 0 lines => callback is not fired...
only when i tried to call callback file manually with correct parameters.. so basic problem is (probably) in the first script, but after hours of googling and studying blockchain API , i found no reason what is the problem

i am trying to create automated receive bitcoin payments via Blockchain API.
I have my API key, xpub, everything. Using php..
here is the part of my code:
part of the code for generating wallet address:
this code works OK, but i have problem with callback php (payment.php).
it's not triggering when the payment is received, however manually, i can simulate the received payment with calling php with correct parameters
the part of the payment.php
my problem is, the callback is never called - can anyone check my code and tell me where i have problem?
thanks
SOLUTION:
The stupid solution: remove .htaccess (or reconfigure) in the web server... simple and it killed 4 days for me
