# Setup Troubleshooting Here is a command that will delete your chain data and any miners you have set up: ```sh rm -rf ~/.lotus ~/.lotusstorage ``` This command usually resolves any issues with running `lotus` but it is not always required for updates. We will share information about when resetting your chain data and miners is required for an update in the future. ## Lotus daemon problems ```sh WARN peermgr peermgr/peermgr.go:131 failed to connect to bootstrap peer: failed to dial : all dials failed * [/ip4/147.75.80.17/tcp/1347] failed to negotiate security protocol: connected to wrong peer ``` * Try running the build steps again and make sure that you have the latest code from GitHub. ```sh ERROR hello hello/hello.go:81 other peer has different genesis! ``` * Try deleting your file system's `~/.lotus` directory. Check that it exists with `ls ~/.lotus`. ## Failed messages Some errors will occur that do not prevent Lotus from working: ```sh ERROR chainstore store/store.go:564 get message get failed: : blockstore: block not found ``` * Someone is requesting a **Data CID** from you that you don't have.
