Hi I have just deployed the canister on ic network using the below command: ```auto dfx deploy --network ic ``` backend is working fine, and both backend and front work fine on the local network, however, on the ic network I get the following error. Anyone knows how I can troubleshoot? ```auto Internal Server Error ``` [https://uaim5-2aaaa-aaaai-qaesq-cai.raw.ic0.app](https://uaim5-2aaaa-aaaai-qaesq-cai.raw.ic0.app/) ---

I’ve been trying to get the root of this with no luck! Any help is appreciated. Should I do anything else after deploy? ---

Can you share more details? Like your deploy logs and, maybe even the code repo of your app? Not sure I can help though but, can compare with mine that works out. ---

Thank you. Here is the log: ![image](https://us1.discourse-cdn.com/flex023/uploads/dfn/original/2X/f/fb3d0abfceb9b45c38461cfb3e70a9a74e22e43e.png) Also the code is a modified version of CanCan available here: [functionland/cancan: A scalable video sharing service. (github.com)](https://github.com/functionland/cancan) It works fine when deployed locally (both FO and BO tested on Ubuntu) But when deploy to ic and loading FO, it gives that error message. Here is a screenshot of it runing locally: ![image](https://us1.discourse-cdn.com/flex023/uploads/dfn/original/2X/f/fd313f768847484b2ba8f2fb3e3131dd0bf56848.png) ---

I think you issue is that you do not have a canister deployed for your frontend. If I check your [dfx.json](https://github.com/functionland/cancan/blob/6bd0d954e8efe7edff00518d7d432355c7989463/dfx.json#L3), there is only a reference to one canister, the backend one, the one you deployed. If I check CanCan [dfx.json](https://github.com/dfinity/cancan/blob/031f31c0f45af72e42416043e1a2415642844d4e/dfx.json#L6) there are two. A backend one as you did and, another one of type `assets` that serve the frontend app. You should also deploy that canister and it is then the one you will access through your browser. ---

Thank you! I totally missed it and was defenitely a problem there. However, I am still getting the same eeor after changing the dfx and now I see assets are uploaded too. Unless it takes some time due to propagation stuff: ![image](https://us1.discourse-cdn.com/flex023/uploads/dfn/original/2X/4/4feed9e08c77765f8113f5ce645ef3f7cdff5b69.png) ![image](https://us1.discourse-cdn.com/flex023/uploads/dfn/original/2X/d/db67d717c82add0e7fd4d2ca332c005026854683.png) ---

It actually works out, just tested 😉. Now that you have deployed the assets / your frontend app, you should use the new canister ID to access it through your browser. [https://bv7wf-6qaaa-aaaai-qahbq-cai.raw.ic0.app/](https://bv7wf-6qaaa-aaaai-qahbq-cai.raw.ic0.app/) instead of previously / your backend cannister [https://uaim5-2aaaa](https://uaim5-2aaaa)… ---
