<title>grant #address connect error code: -5 error message: Invalid address</title>
<link>https://www.multichain.com/qa/6396/grant-%23address-connect-error-error-message-invalid-address</link>
<description>&lt;p&gt;I am setting up two CentOS VMWare servers to use for my private multichain blockchain. However, after successfullly initializing the blockchain on Server2, I see the wallet address provided on the command prompt. For example:&lt;br&gt;&lt;strong&gt;&lt;em&gt;# multichaind chain1@192.168.29.135:7419&lt;/em&gt;&lt;/strong&gt;&lt;/p&gt;&lt;p&gt;&lt;strong&gt;&lt;em&gt;MultiChain 1.0 Daemon (protocol 10008)&lt;/em&gt;&lt;/strong&gt;&lt;/p&gt;&lt;p&gt;&lt;strong&gt;&lt;em&gt;Retrieving blockchain parameters from the seed node 192.168.29.135:7419 ...&lt;br&gt;Blockchain successfully initialized.&lt;/em&gt;&lt;/strong&gt;&lt;/p&gt;&lt;p&gt;&lt;strong&gt;&lt;em&gt;Please ask blockchain admin or user having activate permission to let you connect and/or transact:&lt;br&gt;multichain-cli chain1 grant 18yV9rLuwHkN5UpZRnzpceoWxpVikBoMoADyvK connect&lt;br&gt;multichain-cli chain1 grant 18yV9rLuwHkN5UpZRnzpceoWxpVikBoMoADyvK connect,send,receive&lt;/em&gt;&lt;/strong&gt;&lt;/p&gt;&lt;p&gt;But when I take the provided address, and try to grant it a connect parameter on Server1, I get this error:&lt;br&gt;&lt;strong&gt;&lt;em&gt;[root@server1 chain1]# multichain-cli chain1 grant 18yV9rLuwHkN5UpZRnzpceoWxpVikBoMoADyvK connect&lt;br&gt;{&quot;method&quot;:&quot;grant&quot;,&quot;params&quot;:[&quot;18yV9rLuwHkN5UpZRnzpceoWxpVikBoMoADyvK&quot;,&quot;connect&quot;],&quot;id&quot;:1,&quot;chain_name&quot;:&quot;chain1&quot;}&lt;/em&gt;&lt;/strong&gt;&lt;/p&gt;&lt;p&gt;&lt;strong&gt;&lt;em&gt;error code: -5&lt;br&gt;error message:&lt;br&gt;Invalid address: 18yV9rLuwHkN5UpZRnzpceoWxpVikBoMoADyv&lt;/em&gt;&lt;/strong&gt;&lt;/p&gt;&lt;p&gt;I have tried getting and using new addresses from Server2, but they still provide the same error. I already opened up the port/protocol (e.g., 7419) in my firewall, so I don't know if this is some firewall/security issue -- or something within Multichain I am unaware of. Do I need to reset my chain?&lt;/p&gt;&lt;p&gt;Any help would be great. Thanks.&lt;/p&gt;</description>
