When you opened this thread in the Help section, you should have been provided with a questionnaire. Maybe you didn't get it somehow (which is weird), or you've decided to delete it (and make our life a lot harder). In any case, all the answers to this questionnaire are required:
Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

The Let's Encrypt server sends a more complete error than that. That would clearly identify which rate limit was the problem.
But, I can see from the public logs that you got 5 identical certs yesterday. That is the weekly limit for identical certs. See details here: Rate Limits - Let's Encrypt
Your problem isn't related to getting certs. Something else is wrong with your system if you cannot successfully use them.
That seems like a problem best asked at Cisco Expressway support or their community. But, if you explain what the problem is maybe someone here can help.
For example, I can reach a number of the domains named in yesterday's cert using HTTP (port 80) but I cannot reach any using HTTPS (port 443). That often is a routing problem with that port or perhaps a firewall setting. It is hard to say without much info. One of the domains in that cert, for example: rallye.connectcdk.com
This is expressway server which handls mutilple tenents ; Domains are below
DNS:c03pnsexe01.ctc.connectcdk.com
DNS:rallye.connectcdk.com
DNS:berkshirehathaw.connectcdk.com
DNS:wshealeychev.connectcdk.com
DNS:jimshorkey.connectcdk.com
DNS:ewaldcjd.connectcdk.com
We were trying to renew the letencrypt maully , where it should renew automatically but it is faild with the reason "ACME deploy operation failed: Certificate validation failed " After multiple attempts we are seeing the error " rate limits exeeded"' error.
That's the fundamental problem, but we here don't have any more information about what precisely failed since that error message isn't very specific. I think you'd need to get more information from logs or whatever support is available for that product.
Yes, since acquiring a certificate isn't the problem (you're clearly getting one just fine, just having problems deploying it), rate limits exist to prevent abuse of Let's Encrypt's resources. Let's Encrypt has costs for each certificate they issue for the lifetime of that certificate (and some audit requirements even beyond that), regardless of whether you end up using the certificate or not.
This is a known issue with Cisco Expressway devices, see FN74362 for more information https://www.cisco.com/c/en/us/support/docs/field-notices/743/fn74362.html or Prepare Expressway for Client Auth EKU Sunset in Public CA Certificates for more guidance.
