The new version resolves a TLS compatibility issue with the previous MCU client.
If errors are still seen post install of mcu-cli-1.0.2-49.x86_64 such as: SSL_CERTIFICATE_VERIFICATION errors then use the -n option with the connect, for example:
./connect-qmcuservice -u user -n -s mcu.idm.hal.labThe -n option is to disable the certificate verification.TLSv1.2 protocol now enforces certificate verification. If a certificate is being used that cannot be verified, for example if it is a self signed certificate this will cause the SSL_CERTIFICATE_VERIFICATION errors. -
