 **Note**: The Docker image for the agent is currently unavailable. It will become available for download once a new version is released. Please check the [Releases](https://github.com/leanix/leanix-github-agent/releases) page for updates.
 
+### Troubleshooting
+
+#### Using an HTTP Proxy System
+
+Add the following properties to the command:
+
+```console
+docker run 
+           ...
+           -e JAVA_OPTS="-Dhttp.proxyHost=<HTTP_HOST> -Dhttp.proxyPort=<HTTP_PORT> -Dhttps.proxyHost=<HTTPS_HOST> -Dhttps.proxyPort=<HTTPS_PORT>" \
+        ghcr.io/leanix/leanix-github-agent:dev
+```
+
+> **Note:** Basic authentication is not currently supported.
+
+#### Using an SSL Intercepting Proxy
+
+Build your own Docker image by adding the certificate:
+
+```console
+FROM ghcr.io/leanix/leanix-github-agent:dev
+
+
+USER root
+
+RUN apk update && apk add ca-certificates && rm -rf /var/cache/apk/*
+COPY YOUR-CERTIFICATE-HERE /usr/local/share/ca-certificates/YOUR-CERTIFICATE-HERE
+RUN update-ca-certificates 
+RUN keytool -import -trustcacerts -keystore $JAVA_HOME/lib/security/cacerts  -storepass changeit -noprompt -alias YOUR-CERTIFICATE-HERE -file /usr/local/share/ca-certificates/YOUR-CERTIFICATE-HERE
+
+```
+
+> **Note:** For each certificate you need to insert into the image, add a `COPY` command and a final `RUN` command.
+
+#### Using AMD64 Images on Apple M1
+
+Run the container by providing the following command:
+
+```console
+
+docker run --platform linux/amd64 \
+           ...
+        ghcr.io/leanix/leanix-github-agent:dev
+```
