Thanks! I already tried that but I get the error the 4th and 5th word of the 17 words seed seem to be wrong. I think here they use BIP39 however my seeds seems not to be of that type.
Electrum versions older than 3.3.4 (I think) can no longer connect to Electrum servers due to phishing issues and arbitrary messages that could be sent to users with those old software versions.
A 17-word Electrum seed phrase?
Are you sure that you didn't generate this seed using a different service, like Blockchain.info?
Or perhaps it's a 12-word seed with the extra words being a passphrase? Try to remember how you created that wallet and if you added a passphrase to it.
If there is a chance it's an old Blockchain.info wallet, take a look at this:
Which site? Blockchain.com?
The 17 words part sounds familiar. You may be looking for this:

You also need your wallet ID and password to recover those coins.
