I upgrade the projects Gradle version from 5.4.1 to 6.8.3 and have changed the custom repository to https.
I had a similar issue with maven but after mirroring has been solved. I can build the project without anyproblem with gradle 5.4.1 but when I upgrade the gradle to 6.8.3 then I got the following error:
The server may not support the client's requested TLS protocol versions: (TLSv1.2). You may need to configure the client to allow other protocols to be used.
See: https://docs.gradle.org/6.8.3/userguide/build_environment.html#gradle_system_properties

You get this message when the JRE is missing a certificate. I think you are going to have to install your company's certificate in the docker image's JRE
Your Dockerfile will need to do something like:
FROM adoptopenjdk/openjdk11:jre-11.0.11_9-alpine
// my-company.crt is your company's certificate
COPY my-company.crt my-company.crt
RUN keytool -cacerts -storepass changeit -noprompt -trustcacerts -importcert -alias my-alias -file my-company.crt
