# Troubleshooting
## Internet Computer-specific Limitations and Common Issues
### Migrating Site From Alpha Mainnet to Beta Mainnet
If you originally deploy a static site/app to the Internet Computer's Alpha Mainnet through Fleek, it would have stopped working by now as we migrated to the IC's Beta Mainnet.
Don't worry! It is super easy to redeploy it and get it back live again. Visit the Fleek app, go into the **Hosting Tab** and visit the site you want to redeploy. Once in the site view, visit the **DEPLOYS** tab, and **trigger a new deploy or retrigger the last deployment**. Fleek will rebuild your site and deploy it automatically to Beta Mainnet.
### Canister Storage Limit
Currently, there is a storage limitation involved in Internet Computer canisters. There is an approximate 2.5GB total canister storage limit (meaning, your entire repository can't go above that number). This storage might be increased during the Internet Computer's development
A quick trick to bypass this issue, if you face it, is to **host and store files in Fleek's IPFS storage** and embed them into your IC hosted site with their public URL. View our Storage [(documentation)](https://docs.fleek.co/storage/storage-app/) for more information.
## Build Troubleshooting Tips
Before getting started on specific tips, the most important thing you should check first is to **build your file locally in the development environment**. If it builds locally, but not non Fleek, then you should verify dependencies and follow tips below.
### Verify you are Using the Correct Node Version
When you are working on your site locally, you are using a particular Node.js version. If when uploading and building on Fleek, it fails, you must verify that you are using a compatible Node.js version Fleek when building.
Visit your Fleek account, go into the site's details and into the failed deployment's log. There you should see an error as the following "error node-version...". In this case, it expected version 12 and got 15.2.1.
The fix is easy. You have to visit the **Build & Deploy** tabs in your website's settings, and find the **Specify Docker Image** section. By default **Fleek uses the latest Node.js available, always**. So, you must edit this settings and **add a tag to specify the Node.js version you want to use**:
### Double Check Dependencies
If the problem persists, you might be missing a dependency that you have locally but not on Fleek. To troubleshoot this, visit your **failed deployment logs**, and see if there was an element that was not found. In the example below, you can see the /bin/sh: 1: pnpm was not found.
This means there is a dependency that is missing (pnpm). **How do you fix this?** Even if you put the right build command, if the dependency is not installed like it is locally, Fleek won't be able to use the build commands necessary to create your deployment.
So, to fix this you will need to **Specify a Docker Image** that contains the missing dependency (pnpm in this case). You can create and specify your own, or go on Docker Hub and search for one that is compatible https://hub.docker.com/.
Once you find, build or specify one. Simply hit trigger deploy on top of your failed deployment, and test again.
### Verify the Publish Directory
The public directory is always relative to the base directory. So to use the `public` folder in the project root simply input `public` for the public directory field.
**How do I know if I have the right publish directory?** This varies depending on the framework you use. A simple way to find it is to **build it locally** and see the build folder that it appears and its name.

## Command not found
* If your build fails with the `command not found`, then your dependencies have not been installed. To install your dependencies, upload a configuration file such as `package.json` for NodeJS programs listing all of the required dependencies.
## Build fails with 'exit status 128'
* If your build is failing with `exit status 128`, this likely means that we no longer have access to your GitHub repository. Ensure that your repo is public or that you gave us access by signing in through GitHub when providing the link to the repo.
## Large files or sites
* Sites with many thousands of HTML files can often take a significant amount of time to deploy
## Enqueued builds
* System queue
* This occurs when the number of builds across all of our customers exceeds our current network capacity. When this happens builds will be queued as they come in and be deployed when other builds finish
* Team queue
* This occurs when the number of total builds across all of your sites exceeds the build limit. You can increase your concurrent builds by upgrading your account or by contacting support. If you have this issue, you can cancel other builds that may not be as important.
## My site is not reflecting the latest changes! (Cache issue)
If your website is not reflecting the latest changes, you might have a cache-refresh issue.
A previous cache layer might be being held by BunnyCDN, and therefore you’re seeing the website from the cache layer, not the most updated version.
**Fortunately, purging the cache manually fixes this!** and you can do it right from the Fleek app if needed.
Under the **hosting** section in Fleek, find the affected site, and visit the **Settings section** in the sites details. Navigate to **Build and deploy** sub-menu, and find the site management and Purge Cache feature.
All it takes is a click of the button! Fleek will trigger a manual cache purge on BunnyCDN, and after a minute, you can recheck that your site is displaying the latest cache version.
## Cache Issue - Create React App Service Worker Conflict
If your site is a **CRA (Create React App),** and your site doesn't reflect the latest changes **even after manually purging the cache using Fleek's Purge Cache feature**, you are probably facing a conflict issue with the default `serviceworker.js` configuration.
Create React Apps by default include a `serviceworker.js` that is configured to register a Service Worker to allow the CRA to work offline by caching the content. This offline cache generated by the CRA service worker **conflicts with Fleek's online cached version**.
To resolve this issue you need to **modify the code and call the `unregister()`** function of the service worker to unregister it, and prevent the service worker's offline cache to take over Fleek's.
