The problem has probably already been mentioned in the topics:

There is a client on Android. The AM setup does not complete, but hangs indefinitely.

The log shows:
Contacting account manager at https://bam.boincstats.com/
[https://bam.boincstats.com/] AM RPC HTTP failure: permanent HTTP error

If enable more debugging and look in the program folder, can see:
[http] [ID#0] Sent header to server: User-Agent: BOINC client (aarch64-android-linux-gnu 7.24.1)
…
[http] [ID#0] Info: We are completely uploaded and fine
…
[http] [ID#0] Received header from server: HTTP/1.1 403 Forbidden
…
[http] [ID#0] Received header from server: Connection: close
…
[http] [ID#0] Received header from server: Server: cloudflare

, so for sure the problem is due to Cloudflare.

In the application folder acct_mgr_request.xml looks right.


But acct_mgr_reply.xml contains html from Cloudflare. For example, here is a fragment:
<span id="challenge-error-text">Enable JavaScript and cookies to continue</span>


If open the URL through the browser, then Cloudflare challenge page always opens first.

It should contact https://bam.boincstats.com/rpc.php. Does it actually contact https://bam.boincstats.com/?

Exactly /rpc.php in stdoutdae.txt and in acct_mgr_reply.xml

Cloudflare also blocks long messages.


I'll put it in another place.

Fragment stdoutdae.txt is located at the link https://paste.i2pd.xyz/?2b9ee0b8c71ddc02#CA7PqTcZ7sUmqFQkNkGeMVR6eV13ZYngYy3Ne2BVParJ

acct_mgr_reply.xml is located at the link https://paste.i2pd.xyz/?bcc201fcea813145#DBtvbnSeFK4LgmM5DeTaRr4HPL997dGTYTxtDrQ8kx8A

Can you send me the IP from where the host connects? It would help me to search in the logs. You can use a PM to send it to me.

I access the Internet via TOR. Unsurprisingly, Cloudflare is furious.
I've tried it now and it's connected. The following attempts on other IP addresses are also successful so far.

pf3.prsv.ch [193.35.18.94]
andtor-exit-148.relayon.org [185.220.101.148]
torexitrelay2.duckdns.org [185.243.218.32]
fixecalendar.net [172.81.131.168]
tor-exit-02.for-privacy.net [104.244.77.208]

But not really. I looked at the last two IP addresses more precisely. The log shows that the download /rpc.php successful with the HTTP 200 code, but /get_project_config.php also with the HTTP 403 code and garbage is stored in get_project_config.xml

Added get_project_config.xml to the exception as well.

Now the connections and to rpc.php and to get_project_config.php successful with the HTTP 200 code. And I don't see garbage instead of XML.
Thank you. I hope that the further configuration of the host will go well.

It looks like the problem is solved.
Cloudflare no longer interfered with connections. The host normally received a list of projects (although I did not wait, but pressed synchronize) and worked on them. Some statistics have already appeared.
