I've been attempting to deploy a subgraph on <a href="https://graphql.xinfin.network/">https://graphql.xinfin.network/</a>, but deploying directly to the specified endpoint, as well as trying port 8020, was not successful. What are the possible ways to deploy a subgraph on <a href="https://graphql.xinfin.network/">https://graphql.xinfin.network/</a>?</p> <p><a href="https://www.xdc.dev/images/U-50vFlBY9e0-mRlDs2HMblf1xS1Zu1kpOuxPCOxMn0/w:880/mb:500000/ar:1/aHR0cHM6Ly93d3cu/eGRjLmRldi91cGxv/YWRzL2FydGljbGVz/L2dnYzg0bHMwZzFx/ZWt6b2o1d2hsLnBu/Zw" class="article-body-image-wrapper"><img src="https://www.xdc.dev/images/U-50vFlBY9e0-mRlDs2HMblf1xS1Zu1kpOuxPCOxMn0/w:880/mb:500000/ar:1/aHR0cHM6Ly93d3cu/eGRjLmRldi91cGxv/YWRzL2FydGljbGVz/L2dnYzg0bHMwZzFx/ZWt6b2o1d2hsLnBu/Zw" alt="Image description" width="880" height="303"></a></p>
