升级3.0.0后无法连接3.0版本的tdengine

[vagile-cn]

库版本 3.0.0
Connect后 句柄返回0
但是客户端taosshell 能正常链接

[xleili]

这个是没有成功建立连接，检查一下配置。有报错吗？

[vagile-cn]

没有报错 哪里能看错误信息吗？

[xleili]

看一下你调用 Connect() 的代码？
你是再windows上还是linux上跑的C#。Windows 看C:\TDengine\log，Linux看 /var/log/taos/taoslog0.0。 这个是taos客户端的日志。看看这里有报错么

好的 一会我试下。。我都已经装回2.6了= =

好的 一会我试下。。我都已经装回2.6了= =

用2.6 还有连接不上的问题吗？使用taoshell 可以做正常的查询、插入等操作吗？、
这个日志上又TSC ERROR有一处是语法错误：
08/20 21:44:41.565000 00000904 TSC ERROR 0x5 error happens, code:-2147473920 - syntax error near, reqId:0xd3a7bc7fa75c005c

还有一处是TSC ERROR：
08/20 21:47:57.066000 00000904 TSC ERROR 0x7 error happens, code:-2147473898 - Database not specified, reqId:0xd3a7bc82a30900e0

这两个Error 一般是 调用TDengine.Query() 接口是会报的错。不是建立连接时候爆出来的。配过FQDN吗？

[vagile-cn]

2.6没问题
3.0版本 taos shell 里也是没问题的 一切正常

如果是IIS的web，看一下C:\TDengine\log的日志文件的权限用户，删除这个日志文件就好了。
