Hey, at what stage are you getting this error message?
Could you confirm you and make sure your versions are up-to-date in the order mentioned here: [https://support.ledger.com/hc/en-us/articles/8458939792669-How-to-perform-a-complete-update-of-your-Ledger-setup?docs=true](https://support.ledger.com/hc/en-us/articles/8458939792669-How-to-perform-a-complete-update-of-your-Ledger-setup?docs=true)
Then head to Ledger Live settings > help > and clear cache to refresh its block explorers
After that, try using Paraswap or 1inch from Ledger Live’s „Discover“ tab section and perform a small test swap
Alternatively, if nothing works, try connecting Ledger to Paraswap directly and swap from there interface to see if that works: [https://app.paraswap.io/#/?network=ethereum](https://app.paraswap.io/#/?network=ethereum)
