Wanted! • PHPBB 3.0.8: Blocked/blacklisted IP in SPAMhaus, but SPAMhaus not found it

Title/Job Description:

When older PHPBB 3.0.8 complains about IP blacklisted in DNSBL spamhaus during posting reply to a topic:

./language/en/common.php: 'IP_BLACKLISTED' => 'Your IP %1$s has been blocked because it is blacklisted. For details please see <a href="%2$s">%2$s</a>.',

and links to: https://check.spamhaus.org/results/?que ... 95.221.166

where is displayed:

There is a problem.
The search term you have entered is invalid.

Entering IP alone in the search field shows "130.195.221.166 has no issues"

DNSBL is mentioned in:
./includes/ucp/ucp_register.php
./includes/session.php (full page source code; DNSBL function only, DNSBL function only of a newer PHPBB)
./posting.php (this contains just a condition not a function)

based on session.php, it looks like old URL is:
http://www.spamhaus.org/query/bl?ip=
new URL is:
https://check.spamhaus.org/listed/?searchterm=

when I replace old one by new one, the PHPBB still blocks my topic reply (despite providing to me correct spamhaus URL (which again says "130.195.221.166 has no issues".)
replacing whole function fails with empty page (some error)

Workaround: DNS blackhole check can be disabled in AdminCP, General, Server. config, Security

Is there any idea how to fix this without updating whole PHPBB, please? If reward is needed, I can pay.
