Issue Error migrating from Plesk 12.5 to 17.0

[Marko]

Hi all,

when I try to migrate from my old to the new system I get the following error in Migration Manager. This is what the log says:

I already tried every KB i found and I have the ip address of the server in the trusted ips in fail2ban configuration.

Any idea what I can do?

Hello!
Did you try the following solutions?

https://talk.plesk.com/threads/migration-problem.341035/#post-815997
https://kb.plesk.com/en/127304
https://kb.plesk.com/en/129001

Actually I tried all so far. To be on the safe side I deactivated firewalls on both systems and I deactivated the mod_sec module as well. Nothing changed. It must be related to those lines:

=|2017-02-15_20:37:59,599|D|MT|core.connections.checker||| raise URLError(err)

but I can't find any log in httpd which says there is a block or deny or something.

Any more ideas?

Hello!

Could you please try to access your target Plesk API-RPC manually? For example, could you please perform the following call from shell on your target Plesk server:

curl --request POST \
--url https://<target Plesk hostname>:8443/enterprise/control/agent.php \
--insecure \
--header 'cache-control: no-cache' \
--header 'http_auth_login: <username of Plesk administorator>' \
--header 'http_auth_passwd: <password of Plesk administorator>' \
--data '<packet><server><get_protos/></server></packet>'

If all works fine at Plesk side, this request should return an XML with the list of versions of API which supported by your Plesk server. Or error code otherwise. Anyway, we can narrow it down.
