Just remove HTTPS from address bar and just use HTTP, and it will work :-)

blocks|key|5371193|text|根据this+link的说法，有时问题最终会变成输入参数的顺序。localhost:8545可以在启动geth时启动，如下所示：|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|5371194|>+geth+--datadir+~/ethereum-private-network/chaindata+--nodiscover+--rpc

According to <a href="https://github.com/ethereum/remix/issues/588" rel="nofollow noreferrer">this link</a>, sometimes the issues turns out to be the order of input parameters. 
localhost:8545 can be launched when geth is started like:

<pre><code>&gt; geth --datadir ~/ethereum-private-network/chaindata --nodiscover --rpc
 --rpccorsdomain "*" --unlock 0 --mine 1
</code></pre>

blocks|key|5371214|text|HTTPS不会让你连接到在HTTP上运行的TestRPC。因此，您需要使用HTTP运行IDE。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5371215|http://remix.ethereum.org/|code-block|syntax|javascript|5371216|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

HTTPS won't let you connect to TestRPC running on HTTP.
So you need to run the IDE with HTTP.

<pre><code>http://remix.ethereum.org/
</code></pre>

blocks|key|336092|text|如上所述，从地址栏中删除HTTPS并使用HTTP。另外，我在http://localhost:8545上运行了它|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|336093|geth+--datadir+.+--port+<your_port_no>+--networkid+1234+--rpc+--rpcport+"8545"+--rpccorsdomain+"*"+console+2>console.log|code-block|syntax|javascript|336094|我使用这个，它总是对我有效。|336095|注意:如果你只使用一个节点，那么网络id是没有用的，不管怎么说，如果你只是把它留在那里也没有什么坏处。如果你进一步遇到任何其他问题，一定要让我知道。|336096|entityMap^0|U|L|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@$9|R|A|S|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|T|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|U|8|@]|D|@]|E|$]]|$1|M|3|N|5|6|7|V|8|@]|D|@]|E|$]]|$1|O|3|-4|5|6|7|W|8|@]|D|@]|E|$]]]|P|$]]

As everyone mentioned above, remove HTTPS from the address bar and use HTTP. 
Also, I ran it on <code>http://localhost:8545</code>

<pre><code>geth --datadir . --port &lt;your_port_no&gt; --networkid 1234 --rpc --rpcport "8545" --rpccorsdomain "*" console 2&gt;console.log
</code></pre>

I use this and it always works for me. 

NOTE: network id is useless if you are using only one node, anyway there is no harm if you just leave it there.
Do let me know if you face any other issue further.

Open network tab in Inspect tool, then on connect try see the result. On my case I saw this response
<pre><code>jsonrpc &quot;2.0&quot;
id 16057
error 
 code -32601
 message &quot;the method net_listening does not exist/is not available&quot;
</code></pre>
thus you can see what exactly error happen and do not guess

I had an error to run on web3 provider (localhost:8545)

<pre><code>Not possible to connect to the Web3 provider. Make sure the provider is running and a connection is open (via IPC or RPC).
</code></pre>

So I figured out like below.

I'm running geth on my local and I gave some options to connect with remix and testnet. 

<pre><code>$ geth —testnet —rpc —rpcapi “db, net, web3, personal” —rpccorsdomain “https://remix.ethereum.org” console
</code></pre>

I gave the -rpccorsdomain becuase the remix is on https. 

anyway, check the 'web3 prover' on Run tab in remix IDE. 

Then, modified the address like '<a href="http://127.0.0.1:8545" rel="nofollow noreferrer">http://127.0.0.1:8545</a>' not the '<a href="http://localhost:8545" rel="nofollow noreferrer">http://localhost:8545</a>'.

I don't know the reason why but it worked anyway when I fixed like that.
I made my accounts and did something.

However, I had to redownload the geth again in some reason. (I've changed my pc). and I'm syncing the blocks right now. 
I think the syncing is not finished yet because the the blockNumber is 0.

<pre><code>&gt; eth.blockNumber
0
</code></pre>

so... I'm waiting now but I'm wondering that the error could occur when eth.syncing is not completely done.
