Dear @kim, Thanks for your response. I have balance in testnet for the address : mmsyB5TbdphHD2gGAfRq3osLbdSmceERYs But still I am getting zero balance issue. Based on below statement I am assuming that docker will not be looking at the local node. By default, cert-issuer does not assume you have a bitcoin/ethereum node running locally, and it uses APIs to look up and broadcast transactions. There is API support for both testnet and mainnet chains. Although I dont understand python but looking at code I noticed that api that are used are [https://tbtc.blockr.io/api/v1](https://tbtc.blockr.io/api/v1) or [https://testnet.blockexplorer.com/api](https://testnet.blockexplorer.com/api) when I open first url it redirects me to coinbase,com I there any way I can directly call the api to check if its returning wrong data?

one possibility: what are the contents of your conf.ini? I am wondering which blockchain this is issuing to, so I’d like you check the config. ---

I’m wondering if there is a regression with one of the endpoints we are using. I will debug into this. I should have an answer/fix by tomorrow morning (PST) ---

Also I have highlight one configuration “bitcoind”… does this setting means that it will look for local node? issuing\_address = mmsyB5TbdphHD2gGAfRq3osLbdSmceERYs chain=bitcoin\_testnet _ **bitcoind** _ usb\_name=/etc/cert-issuer/ key\_file=pk\_issuer\_testnet.txt unsigned\_certificates\_dir=/etc/cert-issuer/data/unsigned\_certificates blockchain\_certificates\_dir=/etc/cert-issuer/data/blockchain\_certificates work\_dir=/etc/cert-issuer/work no\_safe\_mode ---

Dear @kim, I have an update, I placed below hard coded statement in bitcoind = False in [connectors.py](http://connectors.py) =\> get\_providers\_for\_chain function and the issue get resolved. This mean that it is for sure related to configuration, btw before applying this temporary fix I tried removing bitcoind and also tried setting bitcoind=False in configration and both of them didnt worked for me. So, for time being I will be using this hardcoded fix. Regards, Danish ---

> [@d.hussain](#): > > bitcoind = False I see; bitcoind is a flag, so if you omit the line, it will have the same behavior. But if you have the following, it will set bitcoind to true: ```auto bitcoind ``` ---

Dear Kim, I tried removing "bitcoind " from configuration and still it is not working. so I guess there is some problem. I have a workaround but looks like this is an issue. Thanks, Danish ---

Is there a way of doing this without bitcoind? I’m facing a similar issue: > [@Insufficient Funds due to SSL error](https://community.blockcerts.org/t/insufficient-funds-due-to-ssl-error/944): > > Hi, I am trying to issue certificates on bitcoin testnet. I got an error and narrowed it down to SSL certificates not working properly. I raised an issue on GitHub and have gotten no response for over a month now… Any help would be appreciated. ---

HI Hussain! And Kim! Im getting better at this, and still crashing but against new walls. I have as you did @d.hussain, and completed my conf.ini file with bitcoind=false, but I do not understand what you mean by this > [@d.hussain](#): > > in [connectors.py](http://connectors.py) =\> get\_providers\_for\_chain function Can you elaborate a little bit further??

Dear @Julian, bitcoind = False was not working for us. So as a workaround we modified the code to ignore the parameter. That was just a workaround to keep moving… Now in our configuration we have completely removed this parameter and added another one as below no\_bitcoind Above is working fine with us. Regards, Danish ---

Thanks for your response @d.hussain! Im a beginer/amateur programer, so everything requires a lot of hard work. I managed to ““publish”” on the regtest version of the cert-issuer ussing the docker version. > [@d.hussain](#): > > bitcoind = False was not working for us. So as a workaround we modified the code to ignore the parameter. That was just a workaround to keep moving… Im trying to do this workaround also but im having a hard time to implement. I tried to see your “connectors.py” but I get an error and can not acces, is it a downloadable version? I also tried to modify the Code, but I think I did not do it right, from the connectors.py from github lines 144 through 147: “def spendables\_for\_address(self, bitcoin\_address): for m in service\_provider\_methods(‘spendables\_for\_address’, get\_providers\_for\_chain(self.bitcoin\_chain, self.bitcoind)):” what I did was replace self.bitcoind for a bitcoind=False as I understood you did but the error persists. Will you show me exactly how you did that workaround to get it to publish? For a non progamer 🙂 I will try to find a permanent solution later, once i get to issue my first certificate. Thanks in advance for all the help Julian ---
