Can't get available migrations from RMT server

I need to upgrade a SLES 15.3 server to 15 SP4 and then to SP 15.5. When doing a zypper-migration on the host server I get a "Can’t get available migrations from server: SUSE::Connect::ApiError: The requested products “Cerifications Module 15 SP3 x86_64, Python 2 Module 15 SP3 x_86_64, SUSE Cloud Application Platform Tools Module 15 SP3 x86_64” are not activated on the system.

The products (repos) are enabled on the RMT server:

  1. Certifications Module 15 SP3 x86_64,
  2. Python 2 Module 15 SP3 x_86_64 and
  3. SUSE Cloud Application Platform Tools Module 15 SP3 x86_64

I also tried to disable the above products (repos) in YaST and then run zypper migration but got the same error message. Could someone please help?

My problem is solved I enabled

  1. Certifications Module 15 SP3 x86_64,
  2. Python 2 Module 15 SP3 x_86_64 and
  3. SUSE Cloud Application Platform Tools Module 15 SP3 x86_64

in the system extension in YaST.
