Joomla URL seems to be misconfigured in Joomdle auth plugin

I am not sure what happened, but I started to receive this error [Joomla URL seems to be misconfigured in Joomdle auth plugin in Moodle] when I used the Joomdle System Check.

I believe it started after I enable the system filter or after I enabled https for the entire site using www.sslforfree.com/ . The System Check was Ok before it.

I saw some threads and I tried to change my configuration many times, but nothing worked.
Follow below my server configuration:
Apache/2.4.23 (Amazon) PHP/7.0.14
Moodle 3.2, Joomdle 1.0.8, Joomla 3.6.5.
core library version: xmlrpc-epi v. 0.51
My course site (gerenciamentodeprojetos.net.br) and my joomla site (escritoriodeprojetos.com.br) is not in the same domain.
Force https for entire site

I am using pt-BR as my default idiom and en-GB as the second idiom.
I configured my Joomdle authentication with this atributtes:
Joomla default language: pt
Joomla SEF enabled: Yes

I also enabled Allow frame embeding.

I am also receiving the message [XML-RPC Error (1): Invalid token] when I tried this url escritoriodeprojetos.com.br/index.php?op...server&format=xmlrpc

Could you help me?

I also tried these recomendations without success:
moodle.org/mod/forum/discuss.php?d=229427
www.joomdle.com/wiki/System_health_check...uth_plugin_in_Moodle

Did you change URLs after enabling SSL to include https? (in joomla and moodle)

This message can also be caused by some error triggered in Joomla, even if it is not related to Joomdle. Set error reporting config in Joomla to none and test.
Also, if you enabled new plugins in Joomla lately, try disablign then and looking at system check.

I tried to change in Manage authentication - Joomdle - Settings - Joomla url from escritoriodeprojetos.com.br to escritoriodeprojetos.com.br
However, when I did that I received other error: Moodle to Joomla HTTP connectivity - Moodle cannot connect to Joomla
Should I changed it in other places?

I only enabled SSL in escritoriodeprojetos.com.br [Joomla site]. I didn´t enable SSL in www.gerenciamentodeprojetos.net.br [moodle site]

I didn't enable new plugins lately.
Error reporting config had been already set to none.

What should I do now?

You can check Joomdle raw replies to see if there is something helpful there.

I checked both files, but I don't know what to do. Could you help me?

moodledata_folder/temp/joomdle_system_check.xml
It is empty.

joomla_folder/logs/joomdle_system_check.xml
<?xml version="1.0" encoding="UTF-8"?><methodResponse><params><param><value><struct><member><name>joomdle_auth</name><value><int>1</int></value></member><member><name>mnet_auth</name><value><int>1</int></value></member><member><name>joomdle_configured</name><value><int>1</int></value></member><member><name>test_data</name><value><string/></value></member><member><name>release</name><value><string>1.0.8</string></value></member></struct></value></param></params></methodResponse>

If file is empty, that means it is receiving a blank reply from Joomla.
Double-check Joomla url in Joomdle config in Moodle, including "http://"
Also, some security software in Joomla may be rejecting the connection...
