Everyone thanks so much for your reply!

It is clear to me now that the SSL certificate sent by Bitpay is not accepted by Electrum and it's not possible to manually edit this. It is something Bitpay has to fix.

In the mean time one can use a decoder (like https://alexk111.github.io/DeBitpay/ ) to extract the payment details. Alternatively you can tell Bitpay you're using Samourai Wallet (which does not support payment protocol), Bitpay should then show the details to manually make the payment.

When paying a Bitpay invoice they allow you to select which wallet you are using. I usually select Samourai Wallet, even if I don’t actually use it, because it doesn’t support Payment Protocol and Bitpay will just show you a regular invoice with an address and amount. It also helps against wallet fingerprinting if you lie about which wallet you use.
Thanks for your suggestion!

So I checked which server Electrum uses and it appears to connect automatically to a (random?) server, besides that it also connects to 9 other nodes. It is possible to manually connect to a single server however this is not recommended by electrum (no fork detection). You can also manually select a server and still have it connect to 9 other nodes.

Does Electrum trust servers?

In short, not really. The Electrum client never sends private keys to the servers. In addition, it verifies the information reported by servers, using a technique called Simple Payment Verification

By default, Electrum tries to maintain connections to ~10 servers. The client subscribes to block header notifications to all of these, and also periodically polls each for dynamic fee estimates. For all connected servers except one, that is all they are used for. Getting block headers from multiple sources is useful to detect lagging servers, chain splits, and forks.

One of the servers, arbitrarily, is selected as the “main” server.

Are client-server connections authenticated?

Electrum uses a client-server architecture, where the endpoints speak the Electrum protocol. The Electrum protocol is JSON-RPC based. The two main stacks the client supports are

    JSON-RPC over SSL/TLS over TCP

    JSON-RPC over TCP

Note that neither option uses HTTP.

The client only connects to servers over SSL (so plaintext TCP is not used). Prior to Electrum 3.1, there used to be a checkbox in the GUI to toggle this but it was removed.

As for authentication, the client accepts both CA-signed certificates and self-signed SSL certificates. When it first connects to a server, it pins the fact whether that server is using a CA-signed or a self-signed cert.

Simple Payment Verification

Simple Payment Verification (SPV) is a technique described in Satoshi Nakamoto’s paper. SPV allows a lightweight client to verify that a transaction is included in the Bitcoin blockchain, without downloading the entire blockchain. The SPV client only needs download the block headers, which are much smaller than the full blocks. To verify that a transaction is in a block, a SPV client requests a proof of inclusion, in the form of a Merkle branch.
https://electrum.readthedocs.io/en/latest/spv.html#spv

This makes me think it is not a Bitpay issue.
Would you agree?

Not sure if this still works but:

https://alexk111.github.io/DeBitpay/

Should pull the amount & address from the invoice.
Have not used it in a really really really long time but back in the day it did the job.

Internet time "really really really long time" =couple of years

Thanks! I'll keep your suggestion in mind if I don't find a proper solution.

It seems it's related to CA certificate a connection authentication, according below

- https://electrum.readthedocs.io/en/latest/faq.html#i-might-run-my-own-server-are-client-server-connections-authenticated

I think the issue here is that your current Electrum server.
Have you tried to change your Electrum server first and test it again? That might be the reason why you got that error.
I haven't tried that yet. I'll try that first.

Unfortunately BitPay doesn't show the actual address in the invoice. It only gives a link (payment protocol?) which Electrum is supposed to use to autofill the amount and address etc. Apparently there is a CA (no idea what that is) in the information that Electrum receives which it does not accept because it is "Not Found in Trusted CA Store".

According to a BitPay support article it should be able to accept a peer-to-peer payment but I dit not see that option when I was trying to pay.

Error when paying BitPay invoice

⭐ Merited by ABCbits (2)
I tried to pay a BitPay invoice. The Electrum wallet is supported by BitPay.

When I click on the link in the BitPay invoice it opens my wallet and then Electrum gives the following error message "Supplied CA Not Found in Trusted CA Store." I can then only click "Ok". Then the message disappears and the Pay To field is blank again. The same thing happens when I manually start and open my wallet and paste the given link in the Pay To field.

I'm using the windows desktop version 4.6.0 of Electrum on a W11 pc.

I've contacted BitPay about this issue a few days ago but their reply is basically useless and suggest the didn't even read my email.

Does anyone know what the error message means? And how I can fix it?

Please post your solution/suggestions here. Do not dm me. Thanks!

Na de wallet te hebben geupdate kon ik de transactie annuleren en staan de coins weer terug in mijn wallet. Nu nog maar eens proberen  Grin

Your transaction is not being confirmed because you sent it with an old version of Litecoin Core. Please update your Litecoin client to Litecoin Core 0.13.2 from either https://litecoin.com or https://litecoin.org.

Ik heb op 10-5 een litecoin transactie gedaan met de litecoin-qt wallet. Helaas vergeten om een fee in te stellen dus de transactie is verzonden zonder fee en is nu al dagen unconfirmed.
Hoe annuleer ik de transactie zodat ik de transactie opnieuw kan doen maar dan met fee?

Ik snap de functie van dit topic niet helemaal. Waarom zou ik bij jou voor 1,7 BTC een tube maple leaf's kopen wanneer je voor dezelfde munten bij een webshop 0,79 BTC betaald? Dat is meer dan dubbel zo duur! Voor de goudbaar betaal je in de webshop 2,67 BTC, bij jou kost die 5,55 BTC.

In de webshop worden de prijzen aangepast aan koers van BTC en aan de edelmetaalprijs. Waarom zou ik dan bij jou het juiste moment moeten afwachten? En niets staat je dan in de weg om dit (voor jou ongunstige) bod af te wijzen.

After reading some reviews, I decided I want an DaVinci Ascent. I recently ordered one from BitcoinAccepted.
I'll post feedback when it arrives.

Received the package today. Well packed!
Fast communication, fast shipping. Perfect transaction!

Just received my coins  Grin Very well packed and coins are as advertised. Thanx for a great transaction SaltySpitoon!

To bad the local postage company made an error on the customs form. They declare it's one item even tho Salty clearly stated on the package that there are 3 coins in the package. Resulting in me having to pay tax over all coins in stead of just one.  Angry

Het viel mij op dat je hier: https://bitcointalk.org/index.php?board=80.0 niet kun zien hoeveel trust iemand heeft. Terwijl dat hier: https://bitcointalk.org/index.php?board=5.0 wel kan. Ook in het Duitstalige deel is dat wel mogelijk: https://bitcointalk.org/index.php?board=35.0

Waarom is dat? En is er iets aan te doen?
