"game not found" forever

[BeppiMenozzi]

Good day!
I'm running a Raspberry Pi 3B+ with "Raspbian GNU/Linux 9 (stretch)".
Skyscraper has always been my scraper of choice because of its fantastic control from cli. I've been scraping a lot of data and, after one year of not updating, I came back to add more. I'm getting crazy because I've been going round an error for days, without any success.
Unfortunately, I systematically receive this exact same error, this is an example with a atarilynx game:

Sit back, relax and let me do the work! :)

#1/85 (T1) Pass 1 ---- Game 'A.P.B. - All Points Bulletin (USA, Europe)' not found :( ----

Debug output:
Tried with: 'crc=F064278F&md5=6A6AFAD666B9942EEBBCA1FBADE6AA0E&sha1=E6BAD23F3572857BD00381B6EC39FBC0AD4E46FC&romnom=A.P.B.%20-%20All%20Points%20Bulletin%20(USA%2C%20Europe).zip&romtaille=188213'
Platform: atarilynx

I made these things:

• updated Skyscraper to the latest version with no results
• the scraped games that fail, were scraped before with the same command
• I got the same failure on screenscraper, tgdb and any other site
• the failed games are present on screenscraper and still, they fail to be found
• network is not an issue in any way, I use it normally and I also could connect with links2 to screensaver.fr
• also the emulationstation scraper fails, with an error that I could not find in logs and appeared briefly, talking about a certificate error, but I suspect that these are two different problems
• running skraper from Windows retrieves the information correctly

I'm wondering what could be done to check what are the problems. Is there a log or other check that I can do to localize the problem?

Thank you very much in advance.
